Cut the flannel so that it is 1 inch smaller than the vinyl on all sides

Lay the vinyl pattern-side down on a flat surface

Center the flannel pattern-side up on top of the vinyl

Starting with the long sides, fold over the raw edge of the vinyl ½ inch. Then roll the vinyl over again (about ½ inch), catching the edge of the flannel. Pin or clip it in place.

Stitch down seam with the sewing machine, starting on the long sides. Repeat on short sides (If you’re new to stitching corners, check out this tutorial.).

If you want to get extra fancy, make a fabric handle for easy blanket toting.
