DIY American flag shorts! Place star stickers on one side and painters tape on the other. Then use Tulip fabric spray paint in sapphire and scarlet. Let it dry then peel off painters tape and sticker! Ps- make sure to put a piece of cardboard in shorts so the dye doesn't bleed through.
DIY: ombre t-shirt (make your own). Might also be cool to try taping or covering a section of the shirt in a pattern/design and then removing the tape after spraying so that you get a really cool imprint on the shirt. Dont know if it will work or not though... just a thought
