Make a… slip cover
Step 1
PLACE your stitching and backing fabric right-sides together and then stitch down the side seams, leaving 6mm (⅛in) of blank fabric outside the border row on the right-side of the stitching.
Step 2
NEATEN the seams or add a lining, then working on the wrong side, turn over the top edge, twice, and catch stitch the seam in place. Turn to the right side and insert the mirror.
