I saw the Quilt Halo on Nancy's Notions video clips. Thought it was creative however expensive. I still think it can be made by finding something I already have or perhaps a trip to Home Depot will help.

Good luck finding a substitute for the Halo for less. The Halo weight is perfect and the coating holds the fabric but is easy to move over the fabric.
The Halo is for small detailed machine quilting, not for all over design. I bought one when Sharon Schamber first had them for sale about 5-6 years ago. At the next Paducah quilt show she was demoing it and let everyone try it. She uses two stacked on top of each other. Like any new tool, if you don't practice using it, it will be no use to you. It took me some time to get the feel of using it but now I can stitch up a small quilting feather or bubbles with the best of them. The Supreme slider does make the quilt glide while quilting. I use the John Flynn frame for all over design and the Halo and slider for detailed designs.
