OESD Top Cover Stabilizer
Using a topping stabilizer on a fabric like toweling helps ensure that the loops or nap remain underneath the stitching. After several washings, some of those loops may begin to emerge from underneath the stitching, especially if the embroidery is a monogram.
I like to use the OESD Top Cover Stabilizer in place of a wash-away topping when stitching monograms. The towel can be washed numerous times and the loops will stay underneath the stitches for the life of the towel.
