Why am I having so much trouble hand quilting on flannel. I have washed and dried it. I have a thin polyester batting. I have tried brand new needles, long ones, short ones, etc. Either I can't get the needle to go through all the layers or once through, I have to pull the needle through with my teeth. Luckily, these are only baby bibs that I'm quilting. Maybe I'll re-think my plans to make a flannel baby quilt.
