WonderUnder is iron on adhesive. The hardest part to doing letters if you use wonderunder is sewing a satin stitch around the edges. That takes A LOT of practice. I have seen shirts done that has the frayed edges which I think would be best for a beginner. After you have your letters ironed on your shirt, go around the edges with a straight stitch close to the edge, then take your finger or a toothbrush and brush around the edges to make them fray. Or do what I did, buy an embroidery machine LOL. I could never do the satin stitch right on my sewing machine.
