I love these blocks! I found a sashing in my stash - it's Ikat Woven Streak by Kaffe and I was saving it for a skirt but I think it's perfect for these blocks. I was told since the blocks are vintage and some of the fabric is somewhat fragil that I should not quilt a lot on them. Does anyone know about this? The cotton seems ok but the feedsack neutral is a little loosely woven (I think)
