Thanks Cathie, but I can't take the credit for finding the site. Another lady on the longarm forum posted the link with a suggestion on using these to avoid hitting side clamps with your machine or as a method of quickly re-loading your quilt onto the frame for some touch-up quilting, etc. When she said this, I thought about this discussion here and figured it might be a good (quick, easy, & cheap) alternative to buying more pipes and cutting your own.
Besides, we're all quilters, no matter our method of choice, and we are all continually looking "outside of the box" for ways to make the process a bit easier. So, like all of you, when I come across helpful info, I want to pass it on.
(Tim would probably have tried to charge you for it... $19.95? $29.95? :lol: )
