My sewing class does a community service project using minkee on one side and a soft slippery I don't know what it is fabric on the other side to make quilts for abused children. The fabric is given to us by the gal that heads up the project. She has made a LOT of these quilts and we do them her way and an alternative way. Her way is sew the two plies together (no batting), inside out, leaving an opening, turn, close up the opening and then sew a 2" border all around it. The border keeps it from shifting. If the border shows signs of making the quilt wonky then we use an alternative method. We measure the width of the blanket, divide by 3, and sew 2 lines down the length of the blanket. So if the width is 45", divided by 3 = 15" so we sew a line down the length 15" in from the right and 15" in from the left. This keeps the blanket from shifting as well.
