Thanks for the tips. I've seen the Sharon Schamber videos on racking a quilt and I like how she has velcro on the pinning edge of the leader, and the has a small leader with velcro on one edge that she sews the backing to the other edge of.
I have the Grace Start Right leaders that have measuring lines all over them and they velcro to the poles. I lined up one of the marks on the center mark on the pole and I mark the backing and top centers and line them up to the leader lines. I just pinned my backing to them and floated the batting. I tried floating and basting the top but I didn't like how it came out so I will pin them.
Someday I'll get around to making the other leader parts as Sharon shows, especially the side leaders.
