Sewing - large hotpad with a removable/washable cover that features four different fabrics

I have made a cover for this large hot pad which I made a while back. I used four pieces of fabric all the same size about 3/4" or so larger than the hot pad and sewed them into a tube by leaving an opening on one of the sides when I sewed them together.  It allows for the cover to have four "different" looks.  The one that is folded over is a very subtle Christmas print that went well with the other fabrics.  This way you can simply wash the cover and reuse it for next time.  Less wear and tear on the hot pad and another cover could certainly be made up if this one should have an "accident".  You can see the other two fabrics in the photo below.
