I often make up several with a boy or girl themed circle in advance to have on hand. I have found that felt is the easiest way to add a letter on top. Now for the simple and easy directions. Iron on your adhesive to a small section of desired fabric. Then use a glass or cup to trace the circle size. Cut out your circle and peel off the paper backing on the adhesive. Iron on to your washcloth.
Next I cut out a small square of wax paper to layer under my washcloth while sewing to act as a stabilizer. A zig zag stitch will easily secure your circle to the washcloth. I then embellished with a felt letter. So fast and simple!
