Last week I loaded a customer quilt at the shop and started quilting. It wasn't until several passes later when I advanced the quilt that I discovered this: eyelashes.
Eyelashes are great for a night on the town. Not so much on the back of a quilt. Eyelashes mean tension issues. Ugly. So then I had to do this: frog.
Smooth sailing after that.
I hate when I have to learn things the hard way! But now I check my tension and check it often.
