Hi! I've never heard of this before. This is interesting. I'm noticing while watching her video that she is not using any clips. She starts by putting a fair amount of pins into the area above where her quilt is hanging so she can grab them as she goes. She first pins the backing fabric to the ceiling tiles - just along the top; sprays the basting spray onto the backing fabric; adds the batting (on large quilts - she has a helper to help) sprays it, then she pins the batting at the top as she works across adhering the batting to the backing, she continues to pull pins from up above on the wall and pins as she goes. Doesn't look like she is using any sort of clips. This is really a neat idea. I'll have to try it - thanks for the new lesson.
