I've just started using my heat transfer (iron-on) vinyl. LOOOOOOOVE IT!!! I get my vinyl at H&H sign supply. I've used several of their brands of heat transfer vinyl and they are all good. On both t-shirts I used SCAL to make the design. I created the shadow in SCAL as well. I double layered the vinyl ironing on one color at a time. The top color doesn't need as much time as the bottom color. I'm very happy with them. I also found some great embellishments and just glued them on with fabric glue (My all time favorite is Alene's Fabric Fusion). Click picture for a better view.
