The next step will be to reduce the size of the backing fabric to be a hair smaller than the quilted top. If you use the quilted top as a template and cut all the way around it... you will likely make a second cut on at least the top and one side. The purpose of getting the backing just a wee bit smaller than the top will be evident in a couple more steps.
Now we'll take the backing fabric and fuse a piece of paper backed fusible stabilizer to the wrong side of the backing fabric in a position where a hanging sleeve will ultimately be placed. For now... cut a small slit maybe 1 inch or so as shown on the photo below. We'll ultimately come back to the slit later and make it larger for the birthing process... For now, all we want is a spot to later insert the end of a pair of scissors. Click on photo for closeup.
The backing fabric will now be placed right sides together atop the quilted top. It is lined up and pinned on all four sides in preparation for stitching a very small seam along all four sides.
Once all around stitching is complete we can move on to the birthing process. But first consider if you might want to carefully remove a wee bit of excess batting on the corners. This tiny removal can help the turned corner be sharper than might have been otherwise. Your call of course... but be careful not to trim too much such that the seam is compromised.
Now increase the size of that slit in the fusible, leaving the fusible paper in place as you begin bringing the quilt top out through the slit.
Carefully push out the corners...
Before we fuse down the slit... I generally use my iron to be certain I've pressed the backing outside edges such that it is not visible from the front view.
You may now chose to add a hanging sleeve placed atop this slit area. No one but you will know the slit is there. ;-) Cool, eh? Thanks Melody!!!
