I secured both ends of everything on the first few quilts on our GrandQuilter, but after I mounted a pin-basted quilt and asked about it here I reconsidered how to do it. I started floating them (but didn't know that's what it was called) and loved the result. I asked our quilt teacher about it and she agreed that floating was preferable and gave me a couple of pointers to help me out. Now that's the only way I do them.
