Plastic topping used on the top side of fabrics such as terrycloth, velour, loosely knit pique, sweaters, corduroy, and fleece. Improves embroidery quality by preventing stitches from sinking into the pile of the fabric.
Tight Spots Tip
We have a favorite way to remove small stubborn bits of water-soluble topping from tight spots like this. Pull away the large pieces of water soluble, then place a damp paper towel over the embroidery and iron it dry. When you lift away the paper towel, the small bits of topping come away with it.
