I also do stained glass & quilt/sew. I had both in a 100sq.ft. room. Did not work out... My DH just removed my stained glass so I would have more room to sew.. and I could still use more space...
I love both crafts, so I refuse to give one up.
You enjoy re-arranging your work space. Can't wait to see pictures. Maybe I will get some ideas from you...
