T shirt companies will not only do a good job, but a more professional looking job as they have access to a heat press (far superior to a home iron), more things to add to your design (anything from embroidered patches to special foil for fabric application).
The 2 photos I have below are some examples of projects to a pre-applied fabric with all over foil Butterfly images printed on the denim (jeans) fabric for a bike cover up slipcover (first photograph shown) to a project which I sent away for application to a bag to hang on a bike's handlebar (photo #2).
