I think I can safely say that I made the strata and blocks more than 15 years ago so I think they have aged properly. I decided to lay out both kinds of blocks together since there weren't enough of either to do much. After I took this photo I sewed them together and it is about 18" x 30". I think it might become the center of a baby quilt or small lap quilt. I thought I would just play around with borders. I hope it gets finished before another 15 years though.
