Pillowcase Turn Technique
The flannel can be one piece or it could be a patchwork design.
This technique works for many sizes, from a baby quilt (shown below) all the way up to a lap or throw size.
(If you are not using plush fleece fabric for your backing,
you may want to attach some fusible batting
to the wrong side
of your backing fabric
before stitching the layers together--see manufacturers directions.)
Place the flannel and plush right sides together and pin around the edges.
Set the stitch length to approximately 10 stitches to an inch,
or use a walking foot if you have one, as you are stitching over a nap
on the plush.
Stitch on the flannel side ¼” away from the edge,
leaving a 4” opening on one side
to turn the blanket to the right side.
Trim excess fabric from the corners and turn to the right side.
Hand-stitch the opening shut.
Place the blanket on a flat surface and pin around the edges and in the middle. The two layers need to be stitched together to secure them to each other. If you have patchwork you can follow the seams in the patchwork as shown in the image below. Or you can just stitch random lines or squares.
