The U is one of those characters of which not many materials or techniques excist. Utee - ultra thick embossing powder - is one of them so I decided to try this. My first attempt literally blew away when I switched on my heatgun. Second attempt was better. This time I started with applying some ink over the fabric before I sprinkled the Utee powder on it. The ink - or any other liquid - will hold the Utee to your fabric when you switch on the heatgun. I decided to combine the colors blue and green. Zapped it long enough so that the Utee melded. Let it cool down and finish it by stitching around the shape of the U.
