I'm a believer in using what you have around the house that can be repurposed. If the coats were gone, could a small bookshelf fit in that space if you have one? On one of those little carts? or even a couple of end tables? Anything with a shelf and a flat service on top can hold lots of stuff. Square plastic containers that you may have in your kitchen can hold scraps and pre-cuts and could be stacked on the top of those bookshelves or end tables.
And, don't hesitate to get someone to go up to your sewing room to bring down stuff you need upon occasion. They won't mind helping you. Just continue to enjoy your quilting and get well soon!
