Quilt Exhibits and QR Codes

Currently, the San Jose Museum of Quilts and Textiles has two Amish-related exhibits. The display of antique Ohio Amish quilts runs into March 2015 but the Modern Amish closes January 3. That's the end of this week! Three Bay Area Modern guilds interpreted Amish for this show. I hope you see them both as they are a very interesting juxtaposition.

One of my challenges this past year was to co-chair an exhibit for CQFA (California Quilt and Fiber Artists.) Primal Green II is on display at the Wallace Stegner Environmental Center located on the 5th floor of the main branch of the San Francisco Public Library through April 25, 2015.

This sign at the exhibit entrance includes detail views of works by Dolores Miller, Reva Bailey, Diane Carver, Jennifer Landau, Caroline Ogg and Virginia Schnalle. The twenty artists who participated use techniques including silk painting, weaving, felting, paper piecing, stamping, dyeing and applique to create their art.

We included QR codes with the displays. These versatile bits of code link to text, video or audio files - basically anything that can be put on the web. Smartphone apps read the QR code and send you to the referenced site. Most are used as an advertising or merchandising tool but we simply wanted to enhance viewer knowledge and interest. So we created audio files discussing how or why we made a piece.

While some companies create QR codes for a fee, freeware exists to generate your own. One of our members wrote a short program to create ours. I think the main difference is where your file is hosted. If you already have a website, it seems simpler to keep it there. Commercial companies place it on their site.

Despite being incredibly enthused, each of us was hesitant to actually record. What would we say? How long could/should it be? Why didn't some famous actress come sweeping in to do the recordings? And a scriptwriter! Ok, the last two are pipe dreams but we were extremely self-conscious about our own abilities. It took several attempts to record without hesitation. Writing a script definitely trumps ad lib.

This QR code links to my audio file for A Daisy a Day, the first quilt on this blog. I posted the code here to encourage other quilters and quilt shows to use this technology. It takes bravery to start a blog. What unique things do you have to show or say? Would anyone take the time to read it? However, it takes a whole new level of courage to publish your voice. If we can do this, so can you!

The are many inventive ways to use QR codes. Upload a bedtime story and print the QR code on the quilt label for your grandchildren to hear every evening. Relate family history, reminisce about a special event or make a prediction about the future. What would you share with your family and friends?

Enjoy the day, Ann

Enlarging (or Decreasing) Circular Blocks

Several people have asked how I drafted the larger blocks in my Steam Punk quilt. It's an application of basic high school geometry. No kidding. The geometric principle is this: similar figures have proportional lengths and congruent angles. That means you always multiply lengths by the same amount while angles stay the same.

Steam Punk quilt with larger and small blocks
How do you do it?

1. Measure your original block and decide how large or small you want the new block.

I won't give the exact measurements of Steam Punk; you'll have to buy that pattern. But let's pretend the original finished block was 4" and the blades intersect the side 1.25" from the corners (Fig. 1 below.)

Fig. 1 - example of original block at 4-inches
2. Calculate the scale factor (new finished block size/original block size) to determine how long the new segments will be. My new block finishes 8" so my scale factor (8/4) is 2.

Draw a new block 8" on each side (4" x 2) and mark the center of the block. Using the scale factor already!

Mark points on all four sides 2.5" from the corners (1.25" x 2). Scale factor again!

3. Draw lines from the center to these points on the side. (Fig. 3)

Using a compass with the sharp point in the center of the block and the pencil at the side point 2.5" from the corner, draw new curves for the blades. If your compass won't expand that far, use your ruler. Place the end on the center of the block and align the ruler through that 2.5" point.

Notice the measurement on the ruler. On my example it's about 4.25".

4. Now rotate the ruler slowly in an arc, keeping the center at the ruler endpoint. Use your pencil to mark many small dots at the same length until you reach the 2.5" mark on the next side (Figs. 4 and 5.) Connect all those points to mark the blade curve.

Note: If you're making a really large block, use your rotary ruler. This tiny ruler just made the photo easier to shoot and see.

Fig. 5 - enlarged arc is drawn
Once your block is drafted, check the central angles by placing your original blade and triangle templates  on the new block pattern at the center. The sides should line up perfectly. The templates are just shorter than your new length.

The radius of the center circle will also be multiplied by the scale factor. So if it was one-half inch originally, it will be one inch in this example (1/2" x 2).

Trace each template, add seam allowances and you're ready to go!

Hope this helps. Let me know if you have questions.

Enjoy the day, the holidays and the New Year!

Curves Continued

One of my difficulties with this quilt has been limiting the size. I can't see the edges of the quilt. At one time it seemed it might not stop before the edge of the design wall. Yikes.

Then I thought of using string to outline a rectangle. It's a bit more visible in the photo below. Basically, I'll square up the quilt near those lines but at least I'm aiming at a general size now.

I was planning to make some straight-ish sections to fill in the background but most of the quilt was already filled once I marked an area with the string. So I just made a few more to finish the corners.

I also rotated the bottom right curve. Q just wasn't cutting it. (That's what last week's photo looks like to me.) This layout connects with the rest of the quilt better. I'm still thinking about the other curves.

Curve Quilt Progress

I'm learning so much while working on this quilt.  More of these sections need to be sewn together but it's almost impossible to take one off the design wall and get it back in the exact same place. I machined the coral/orange white circle and interior but may switch to hand sewing or Vikki Pignatelli's method for sewing curves.

Vikki machine appliques the curves with Invisifil thread: 100-wt. 2-ply polyester. My takeaway from her Crazy About Curves class was to turn narrow seams on the top layer and blind stitch from the top (although I recall using nylon monofilament at the time.)

Curve Quilt detail
Tight and gentle curves  and some straight sections are all needed. Most of mine are mid-range radius. More curve variation would help.

I thought Sherri Lynn meant to assign a specific mood to each single color based on how one felt that day. I chose these colors but felt the mood assignment was artificial. Anyway, here's my explanation:
  1. red - energy
  2. coral - happy
  3. orange - annoyed
  4. green - health
  5. white - tired/sleepy
  6. blue - peaceful
  7. yellow - questioning
Upon re-reading her post I realized her moods are more general, covering a section of values and shades rather than an individual color. This makes more sense to me; a group of values conveys my mood more than an individual color. 

There is very little yellow in my stash. Rather than buy fabric I removed that color. Then I used a bit of each of the remaining colors and sewed some curves. The curves are too ambiguous. If all the colors are in each curve, it's hard to distinguish one curve from another. So I switched to smaller groups of two to four colors. Each color can have one or more fabrics. This is working better.

It's obvious in the photo below which curves were sewn first and which were sewn later. I also decided I needed a new, discrete section rather than having everything unfold from a single center. That's how the Q appeared in the bottom right. It may be too disconnected from the rest; we'll see.

Curve Quilt in Progress
Every time I add a curve, the quilt gets bigger. It's a bit like children - we keep them once they arrive. :-) I don't want to trim any of them away but I don't want a large quilt. Continually adding curves is not helping me square it up. Perhaps I should piece strips in straight-ish sections to finish it out. Another point to ponder.

The technical points are starting to pile up. I'm deliberately not looking at anyone else's postings again until mine is sewn in order to see how I work this out. It will be fun to compare later. And having completed one, I'll have a better understanding of how and why others made their decisions.

Enjoy the day!

And That's What Happened to the Comments

I'm very grateful to Google for giving me a free Blogger account. In general it's been easy to use. Occasionally I've added some html and some buttons.

I don't have many followers; I'm not trying to make money; I simply wanted a new way to connect with people who share my interests rather than being limited to a guild. Blogging gives me a small platform, flexibility in the length, frequency and amount of my writings with time to think before I publish. There's a way for me to quickly link to sites I like to read as well as a way for people to respond to my posts. I think of it as a modern combination of a diary and letters to friends. Reading comments and recent posts on blogs I follow has become part of my routine.

But I remain grateful to Google for this opportunity. So I've tried to repay them by trying out new features they publish. Just after I started my blog they came out with new templates and I switched to one. Not that I cared that much but it seemed a good way to give them more test subjects. About a year ago they suggested linking Blogger to Google+ and I went along with that. I lost some comments when I linked them. It didn't make me happy but I thought I was doing the right thing to help the company that helped me. But with that link I became a No Reply Blogger when commenting on other sites. Not what I wanted.

So I unlinked the accounts and thought that was done. Wrongo. BEFORE unlinking the accounts, I should have to gone into Google+ setting and unchecked the box to use Google+ comments. (It turns on automatically when you link the two but must be manually turned off.) Only after that is done will returning to the old Blogger profile have a real effect. See the post by PeggyK in Google's product forum here for a better explanation.

The downside is all previous comments on my blog have disappeared. Again. Somehow they were linked to Google+ and not to my blog. How sad. Some of the discussions we had in the comments section were better than the original post. It was like losing letters in a fire - there is no recovery.

I think things are set so you can now comment without being on Google+. I refuse to sign in on other platforms to leave comments and didn't realize I had this relic on my site. I'm so sorry all the old connections were lost but hopefully this will work equitably for us all in the future.

Enjoy the day, Ann
