Each of these blocks are of a different fabric but made the same. I think I will print out my picture of the block and then play with it regarding embroidery. I can mark on multiple copies to find something that works for me. I have many butterfly blocks made in the 1930's but this is the most unusual of all. I think originally I bought it to take the body fabric for blocks and discard the rest but I just can't do that now. I restore old quilts and use vintage blocks and try to do the best I can in making quilts come to life. I will add sashing and borders and this may not turn out my favorite, but when finished, I'll post the picture. I am also making 3 other quilts now from vintage blocks.
