Thanks. I thought of that, the old lady even has a sewing machine...but then I'd have to be nice to her.You can buy felt by the yard off a roll at your local WM cheap and make your own. If you can't sew it together you might use velcro tape, also available in the craft section of the same store. May not turn out so pretty, but should be functional for your needs.
McDermott has nice 1x1 sleeves for 16bux. https://www.mcdermottcue.com/750941.phpWhere can I purchase some case sleeves? I have a bunch of hard cases and stack them in my closet...I would feel better if they were in felt sleeves to protect them a little. I found the pic below from an old post (not mine).
