While I have another machine - the HQ16 - I made my straps with velcro and bought clamps I could manipulate at Ace Hardware. I used folded store bought bias binding I had from my sewing days to attach the clamps to the velcro straps. I had to try them to see if I could use them. The clamps with my frame were too hard for me to use.
I sewed side leaders out of ticking and made a sleeve at one end for 2 painter stir strickss, one on top of the other, in the sleeve. I then attach my velcroed clamps to cleeve with the paint stir sticks. I pin the other side of the side leaders to the quilt back. Works just great.
I tried the Red Snappers side pieces but they are way too difficult for me to manage. I do use the longer Red Snappers for the quilt top and my QuilTak for the quilt top bottom. The RS are easy to manipulate because I bend them inot position. I know it sounds bulky, but it works best for me this way.
