As a LAQ, I've noticed the following:
The more stitching, the firmer the quilt.
W&N is great for wall hangings, table toppers, etc., but not for cuddly quilts.
Hobbs POlydown or Heirloom cotton makes a cuddly quilt, as does the Quilters Dream cotton.
A finer thread does help, but it's mostly the amount of thread that makes the difference.
Hope this helps :)
