I have finally had a go at putting an applique onto a tshirt. Thanks to Karen for all the advice she passed on to me. I have used vlisofix to attach the applique to the tshirt, then attached some vlisene to the back of the applique area to help with sewing the applique on. I have used various quilting books on advice of how to machine sew appliques in place. My Mum gave me the book that had this design in it - a US book from when she was in a quilting group there. I am very happy with the results and love the thought of being able to make one-off originals for my daughter! Plus, she needs some new tees!
