First step was to sew all the mediums. I was determined to finish these off so you can see I ran out of a coins in the middle. I could cut more strips or sew two narrower columns together to get the wider column.

Another idea is to add in a strip of contrast. And move the green column to the far right.

I thought it still needed the light and dark value columns until I realized this is a great background to applique on. Hmm. Change of plans. I've been wanting to add applique to a Coin quilt. This will be Chinese Coins VIII...
Enjoy the day, Ann
