here are some large hex's I made for a friend. made smaller ones for coasters too.

How about trying a crayola quilt? You can take pre-cut white squares, copy a pattern from a coloring book, then color.

buy some quilting magazines to read. Keeps me busy for a good long time. I could page through the pictures forever. I also have a book on fabric folding. Maybe you could get a link for some free fabric folding sites and try it out.

Get a jinny beyer pattern and cut some pieces to hand sew. It might never get to be a finished quilt, but will keep your hands busy!

When my husband had a 6 hour surgery last year, I took my blades for a dresden plate and hand sewed the top of the blades and had enough time to hand sew the blades together. You're not crazy - if I don't have something to do with my hands I drive everyone else crazy. Take care and best wishes for her surgery.

I have been in your shoes, and the anxiety that comes with having nothing to work on is crazy. You have my sympathy, maybe you could find a good book just to relax and read. Hope all goes well.
