Is that the Japanese Pine Bark pattern? I just saw it for the first time at Road to California, and looked it up. It was done as background for a silhouette of a twisted pine tree. The effect was very oriental and dramatic!!

About the bias thing, if you starch your fabric well before cutting, it really helps prevent stretching. And you have to handle the fabric carefully, and no pulling!! ;)

I love that pattern!!! Good Job :D:D:D
