Sharon Schamber has a video on YouTube about board basting.

It is the only way I baste my quilts now and it works! Some people use pool noodles with a dowel or pvc pipe inside to stiffen them, I have never done that, but it looks like it would work as well. I hand quilt my quilts and this is so much easier than anything else I have tried, plus no getting down on hands and knees!
