I machine quilted the second Project Linus top to practice on since it's simpler and I wouldn't cry if I completely messed it up. It's not top quality but it's done. It kept trying to distort on me.
I started to use spray baste, but then I remembered an unfortunate incident with some quilted shams for my bed. The spray baste bled through the top fabric and stained it. Must have sprayed too much, but I was gunshy to try it again.
Oh, well. Live and learn. I have to wash it since Queen-of-all-she-surveys wallowed it good and proper before I could shoo her off. Cats are born quilt-testers.
