Thanks for all of your responses so far!!! I am definitely not going to use the Hi-Loft, but am still thinking of using the extra-loft (3/4" -- 1/2" thick). Rather than pinning would it be good to baste at maybe 4" intervals? Any other tips for working with this thickness? The suppose I could use a thinner batting, but I really don't want a flat-looking quilt. I want it a bit thicker, but still don't want it tied, and I don't want to buy an expensive batting.
