Seams are thick
I have made a top for a doll quilt out of a variety of fabrics because children like to feel different textures. There is some flannel, plain cotton, minky, and a soft thinner courdoroy. I had planned to just use a an extra piece of flannel as batting but the seams are too thick. When I spray basted the layers together, I can feel them through the layers. So far, I've only made baby quilts and used flannel as batting so I know absolutely nothing about batting. Any recommendations? I do not want this to be too thick or heavy for this precious little 3 year old to play with it.
Thanks in advance.
