I'm just making my first T-shirt/jersey fabric quilt, from my two oldest granddaughters' favorite baby clothes. What a challenge it's proved to be! All that cutting, stabilizing with Pellon feather weight...I've got 10 8"x8" squares done, but am now noticing the weight. What do more you more experienced quilters in jerseys suggest as a backing and/or inner fabric? I'm considering sashing with a good quality flannel, and maybe use it as a backing fabric as well. Does it really need an inner layer? What about machine quilting other than longarm? Any suggestions?
