It is a pleasure to be in the company of so many talented and dedicated women. I've enjoyed reading this very long thread!
I guess the most unusual thing that I have ever made was a new fabric seat for a baby walker that was probably originally sold in the 1950's. It had a wire frame and the little wooden beads on the front of it as play things. My little grandson was visiting and we needed a way to corral him a bit. DH dug this walker contraption out of the barn's hay mow. So I cleaned it well and made a new seat for it. It didn't last long, my grandson was a very very fat baby and he ripped it the first day we put him in it, lol! I never knew a baby could have such a perturbed look on their face until that day.
