Un-sponge - 1 side cotton print / 1 side cotton terry towel in a coordinating color. The inside is NuFoam. (This densified foam batting is mildew-resistant and non-allergenic ) Just toss it in the wash with your towels.
Some photos shows 2 sponges so that you can see front and back, only 1 is included per item purchased.These are made with fabric left over from when I make the napkins, un-paper towels, etc, so the size will vary- the smallest I have had so far was 3x5, the largest was 5x5- so most will fit in that range.
Size, pattern placement, and top-stiching may vary from photo.
