I purchased some freezer paper at Walmart, then I freehanded some funny skulls right onto the paper -dull side! (I used magic marker, but next time I will use a pencil (It made the paint bleed in a little). You could also trace something easy enough since it's see-through.
Get a good exacto knife and start cutting, this part is tedious, but believe me when I say,
scissors don't do the job!When you are all cut out, dry-iron your paper--shiny side down on the shirt. And you are ready for paint! I went to JoAnne's and got the fabric paint in the small bottles, but I also needed spray fabric paint and they didn't have it, so I ended up at Walmart and found they had a better selection of regular fabric paint as well as fabric spray paint (plus it was cheaper)... so if you have a good Walmart nearby, go there... if not, go to Micheals, because they have a great selection as well!
For these I obviously used the spray paint... I bought the "pump spray" if you can, find the continuous spray! My hands got SO tired. It does cost a little more, but I am sure way worth it. Although, the pump spray has a smoother texture.
When the paint is fully dry.. the bottle says it takes 4 hours.. but I did these outside in direct sunlight and they were dry in about 40 minutes. Anyway, when they are dry carefully peel off the freezer paper, then lay a piece of paper over the painted parts and DRY-iron on top of that to set the paint.
To cut my work in half I was able to use ONE stencil for 2 shirts. For the shirt below I used a paint brush and the paint in the small bottles (above) and painted inward from the paper to reduce bleeding. I think they turned out pretty cute!
