This project was inspired by one from Glitterbombers. We use their art membership and its chock full of great project ideas! I highly recommend it!
Draw your design with glue on your shirt. We first drew it on paper and traced with sharpie and placed this between the shirt layers and used it as a template to trace. We placed flexible plastic cutting boards with wax paper between the shirt layers so the glue didn’t bleed through. Cardboard would also work well, I believe. Let the glue dry overnight.
We then painted our shirts with the dye-na-flow.
I used a pipette to withdraw the dye from the bottles to prevent spilling. I diluted it about 50/50 with water and used a paint palette. We painted it on with paintbrushes. It behaved much like watercolor which was delightful! We then let this dry overnight again.
Soak the shirts in a tub of water for about an hour then rub off the glue. Dry in the sun or clothes dryer.
