Teaching my big sister to use my longarm quilter. I'm a 'take charge' type person, so holding back is a challenge and a half. It's going well. We haven't had a fight - yet!
The first quilt we did, we made every terrible mistake you can make - in spite of my 'expertise'. It's good to learn how to handle those mistakes with a guide nearby, but I wish we hadn't made them. The quilt came out just fine, by the way.
Second one has gone better, but now, at the end of the quilt, we have some serious fluting. I explained how I handle that, but left her to make her own decisions. Later we will finish the quilting.
