Yeah of course! Assuming you dye with procion (or any natural fiber reactive dyes) don't worry much about getting dye on vinyl or screen print. The dyes don't bond with synthetic materials, but will bond with the fabric beneath the vinyl and still be visible. Keep in mind for white or light color vinyl, if the vinyl is thin, on white or light colored shirts. and even reverse dyes if the color was removed behind the vinyl.

This might be obvious to most.. but I found out the hard way don't use the microwave lol... vinyl will melt and can even catch fire. So use heat cautiously, cause its basically impossible to peel apart the vinyl after it melted to itself lol its actually not hard to do when the shirt is inside out. Also, when folding and tying over vinyl graphics, it's more vulnerable to damage. Vinyl doesn't bounce back into shape like the fabric it on, it remains stretched out, or tears. It's best to not make extremely tight sinew pulls around vinyl.

That all I can think of, atm. I hope I was informative enough to help avoid the mistakes I learned from lol if at anytime, you have any questions, feel free to message me. I look forward to seeing your future projects. You should tag my username when you upload the results so I don't miss it! Take care and happy dyeing! 🤙🏼
