I am going to say give it up. I did. About 10-12 years ago I was so frustrated that I wasnt "happy" with my finished quilts.
Kept my sewing machine, table and cutting table but gave almost everythingelse away.
Then a couple of years ago, I got the bug again watching a TV show. Got back into it. Bought a new setup. Now I am hooked again.
I dont know if it that the technology is better, that I am more patient, that I take my time now or what but I dont have nearly the frustration.
