Hi Welcome...how about just doing a scrappy simple 9 patch as a starter? They make good donation quilts or a nice lap size for watching TV.
Bless you for your determination! Have you read the Elm Creek quilters Books? The lady in the series had a stroke and retaught herself to quilt again...good healthy reading! Someone gave me the first Trilogy when I had my knee replaced about 6 years ago...got hooked on the series and loved them.
