Several times in the last few weeks I have been asked about afghans, what fabric to use, why and when. In the past afghans were often designed to be stitched on Hearthside (do I have that right?) where there are distinctive separations between the blocks. I did such as afghan when I did Nature's Home, which I finished in 2006.
I hope I have answered all the questions. If not, let me know and the discussion can continue.
