How do I “heat set” a shirt I just painted on with fabric paint?

I started by drawing my design with chalk and then drew over it with a black Deco-Paint marker. The pen states that I should “heat set” the paint, but I’m not sure how to do this, especially with chalk still on it a little. Do I just iron the shirt to do this? Would it be a good idea to dry clean it instead? Or is there another way to do this…?

  1. I used to paint on shirts and after the paint dried I would heat set them by putting a brown paper sack (use a side of it ) and put the sack over the painting then low heat iron over that. This heat sets it. Hope this helps.


  2. i generally use fabric/acrylic paints. but i’m sure the same technique holds true for markers.
    make sure the marker color is completely dry.
    then reverse the fabric & iron over the design [do Not use steam].
    you can add a layer or old cloth between the painted design & the ironing board to make sure none of the paint comes off.

    hope this helps

    all the very best 🙂

  3. You can also use a “pressing cloth” or an old t shirt to heat set with an iron, or turn the project inside out and put it in the dryer for 20 minutes on high. After it’s been heat set you can wash out the chalk marks by running it through a short cold wash cycle(again, inside out).
