I am thinking of buying the batting that has already been spray basted. Saw it at JoAnn's but did not take the time to read their instructions. I was not happy with the can of spray basting I used it really stuck and gave me problems when I tried to quilt on it. Residue stuck to my needle. Thinking maybe I used too much, so next time I will try it on something smaller than a quilt as a test. Works good on pot holders.
