I was cutting the sashing and border for littlest goddaughter's quilt. I sensibly cut the longest, widest strips first - for the border - and put them on one side.
I have now done all the sashing, and the patterned border, so I reached for the pieces I had set aside. Yes they were there - I bet you thought I was going to say they'd disappeared! However, I found that I had cut two of them instead of four, and what's left over of then fabric can't reasonably be made to work.
Now I have to wait for another 1.5m to be delivered before I can get on with it. Aaargh!
