Years ago I acquired a sewing desk and stool. I would not at all be surprised if it is over 60 years old. It still has, well now I should say had its original seat pad and covering. Because of its age, it was getting the funny old smell. I've been needing to redo it since I got it, and today I finally decided to accomplish it.
log cabin quilt shop. I used the old cover to measure out how much of the new fabric I needed and I just grabbed the smallest bag of batting that they had.
I should also note that I doubled my fabric over for extra protection, so I only seamed 3 sides since one side was folded over.
