I made some cute little stencilled tshirts using freezer paper and fabric paint at the weekend
I just printed an outline on the freezer paper with my regular injet printer and cut it out. I then ironed the freezer paper, waxy side down, onto the tshirt. I painted the stencil useing screen printing paint, waited for it to dry and then peeled off the stencil. I ironed it afterward to set it but check your paint instructions for how to fix it
Theres some great silhouette clip art available on the internet to use if your rubbish at drawing like me!
