Cotton batting Never again!
I had a roll of Hobbs cotton batting with scrim I thought I'd use. Ugh, I use adhesive spray and it is awful on cotton batting. It does great on Hobbs 80/20 batting so I didn't think there would be a difference. Those that have tried spray basting and had a big mess with wrinkles and puckers it was probably because of the batting. I've never had this much trouble with spray basting before and couldn't figure out why so many did. If spray basting was used on this type of batting no wonder! I'm almost to the point of taking out the quilting I've done and toss the batting.
