Insert a piece of cardboard inside the shirt, maybe line it with some waxed paper as well.
Load a small paintbrush with one of the paint colors and aim it at the shirt. Just wing it! Just like you were throwing one of those lawn darts overhand. I did each color 3 or 4 times, repeated some of the colors until I was happy with the design.
Next I added some super easy flowers. No artistic ability needed. Just brush and blend some yellow and orange petals by adding curved strokes.
Add in some green curved strokes for leaves here and there along the line of flowers.
For the flower centers, I used Iced Crystal and some of the pink. There was quite a bit of blending going on. Again, no rules!
That’s it; now just let it dry for a couple of hours and then transfer it to a clothes hanger. It will need to sit for 48 hours before going in to the washing machine.
