I just watched my first ever Craftsy class this weekend, it's a FMQ class by Leah Day. At the end she had some extra stuff and one extra was a clip from another class where she shows her method of basting. She uses a couple folding tables and wraps wide elastic around the legs which she then stretches up and pins to the backing, which then pulls the backing taut and keeps it super smooth.
I think I'm going to try it...I'll need to buy another folding table (I have 1 but will need 2) but it looks so much easier (and less wasteful) than my current method that involves using up half a roll of blue tape and crawling around on the hard floor. I would LOVE to get the basting step up off the ground...my back and hips aren't as young as the rest of me, LOL. And I still get puckers sometimes with my current method...Leah's method looks like it'd solve that entirely.
