Thank you for the great instructions.
I sent a link to your post to my DH and he went right out to his workshop, found a chunk of wood and made me an ironing board top. Then he helped me staple down batting and I just happened to have some heavy-duty fabric for the top. Since he used an offcut from something, mine isn't as big as yours, but I told him I was willing to start out a little smaller and see if was too annoying.
I LOVE IT!!
A quilting friend came by with her DH soon after we finished and he had a good look at it. Now she's going to get one, too.
See what one little post has done?
