Sewing - medium hot pad with a removeable and reversible cover - GA

I made a cover for another of the hot pads I made a while back.  It is about 13" x 10" and had cotton, metallic insulation and knitted wool batting with a cotton flannel to hold all the layers together.  I stitched up a cover (sleeve) for it using four different cotton fabrics - red guitar, checkered green, rust cross hatch and multi coloured uneven stripes.  The pieces were all the same size (14" x 11") and I stitched two together on the long edges to make a tube.  And again for the other two.  I turned one inside out and inserted it in the other one (right sides together) and stitched both ends leaving a gap of about 4" on one of the ends.  I turned the whole thing inside out and pressed it flat.  I hand stitched closed the opening I had left and then added top stitching to both top and bottom edges and to the two side seams which should allow it to be restored to it's rectangular shape after it is washed. Pick your favorite fabric on the day you use it and after using it simply remove the cover and wash it to be ready for next time.  Small enough to fit in most drawers and enough variety to rise to every occasion.  It will accommodate several small hot dishes or a 9" x 13" casserole.
