I tape the backing to the floor and spray baste. Three quilts, no puckers so far. :)

Well done
I have a friend who uses that spray but obviously not properly as she has more puckers than a gathered skirt LOL
She made a quilt for another friend & it was a real mess so I am trying to fix it No squared edges before she started & terrible colour blenders everything was skew wiffed border on one side was 2" & 6 " on the other side
I shouldn't complain as she gave me a few pointers on how to start & THEN I became addicted !!!!! :roll: :roll:

Add to that: Do you pin more than hand-width apart?

Two suggestions - 1 - Use Spray Baste!!!
if that won't work - try Sharon Schamber's handbastint technique http://www.youtube.com/watch?v=bhwNylePFAA
oh oops maybe 3 suggestions- starch your backing!
Good luck !!!

Thank you SO MUCH, craftyone27! I had heard of using boards to help you baste on one of the threads a while back, but I didn't watch it thru. This time I did. I'm going to try it, and I don't think I'll be basting with pins agsin. Plus, I can sit down to baste! That will sure help my back.

You are very welcome! A fellow quilter posred the link on a thread of mine - so I figured I would pass it on. The technique worked well for me. I used flannel backing and I still ended up with a few small issues but nothing compared to my first attempt with pins. It is much easier on the back as well.

I had problems with puckers too til I started using basting spray. No puckers now.

Most longarmers will baste the heck outta em for cheap!!!!!

Great suggestions.
