Needed a break after air sewing for 10 minutes!
These are going together really well, my accuracy is improving. Some really yukky colours here! There is enough variety in the hundreds of patches ready to sew that it will all look fine.
I am using up reels of gifted poly thread to make these. The received wisdom is never use polyester with cotton: the more modern threads for quilters are cotton coated polyester, I don't see the difference! I do not use polyester for the quilting especially for charity quilts, as someone may take it into their head to iron it!
