I had thought I had too many for one quilt. I was right. I have made strips enough for 2 quilts at 60 x 72". 560 bow ties in each. One of these is for me, another a gift. Here are the strips hanging over the door.
I sewed a few pairs the wrong way round: I have a baby quilt to do in the summer, problem solved, I sewed a few more, now all I have to do is add a plain border to bring it up to cot size. I don't know the sex of the baby yet, so I threw everything in there!
Leftovers: enough for another 5' x 6', or a fancy border for another quilt. I knew I had overdone it, but really!
