The fabulous fabric glide
 

Has anyone used The fabulous quilt guide? I was at the quilt show near Philly, and picked up a set. Of course I found them online cheaper. There was someone else selling a different version of the set for a lot more.

I have a similar one that come direct from Bernina but find that just using my hands works better. The guides are just something else I have to look after and keep in correct position.
