I was at a swarm awhile back and a lady demonstrated how to add designs to t-shirts , bags,etc with fabric paint , vinyl and your cricut. This is my first attempt. I  used the Cuttin Up cart for the lettering and cut it out of the vinyl, took the backing off and stuck it onto the t-shirt, making sure it was all adhered. Using  a little foam paint brush I then painted the lettering. Once thepaint was dried I removed the vinyl and this is the result.  I thought they turned out pretty good.
