I absolutely love Warm and Plush. I bought a roll of it and I use it every chance I get.
What size do you normally cut your binding? I typically cut mine 2.5 or 2.25 and it's always been fine, but I also machine bind so I don't know if it would make a difference vs hand binding.
Love this batting so much. Hope you love it too! I used it in both of my little ones' quilts with a flannel back and both girls love how cuddly it is.
