I will just tell you my experience. I made throw pillows for my sofa and Crosstitch on Aida cloth,the fronts. However, the DMC floss eventually started breaking. I don’t know if it was because we use pillows at our backs and sitting, moving, rubbing the fronts or what, but the DMC didn’t hold up. Just telling you my experience so you can think about it, before you put in all that work….another thought, you could x stitch a wall hanging while you’re convalescing. I have several in frames, largest 16x20, but you could also hang like a quilt wall hanging. A wall hanging wouldn’t have the friction against the DMC like my pillows did and when you needed to wash, you could hand wash. Good luck!
ps. Here is my 16x20- I nearly went blind stitching these quilts, especially all the gold shading-lol - it took me longer than to piece a real quilt!
