I used to make baby/kid quilts using these pillow panels. To get the front and back to match I'd sandwich my backing, bat and front together. I'd then put the back of the pillow panel on the back of the quilt and stitch around the stitching line. I would then cut the seam allowance fabric away very close to the stitching line. For the front I would cut away the the seam allowance and then place the edge of the pillow panel along the stitching line all the way around and pin it in place. I would then use a satin stitch to go around the outer edge of the front of the pillow panel. Since you are lining up the front to the back using the stitching line you are able to catch both sides at the same time and also secure your layers together. Wow, does this bring back memories when my kids were little.
