Has anyone used these? I was just watching a video and wondered if they are as easy to use as they look? The instructor was using a small quilt. How do they work on a queen or a kind size?

Not sure what you are talking about. Do you have a picture or a link to the video? Thanks

Don't have a pic and don't know how to link, but if I found by Googling octi-hoops. Shows where my mind is...I can't remember why I wanted to know! Honestly, I'm losing it here!!!!
