Draw your robot on a piece of cardboard.
Cut the stencil with a craft knife
Iron the fabric, and glue tac your stencil on it, TIP: don't make the heart because the type of fabric I used just made the colour run :/
Get your Fabric Paint, I had red
Get an old sponge and put some paint on it
Fill in the Stencil
(see why I told you not to do the heart with this kind of fabric)
Make the outlines with the permanent marker.
Sew on =D
I put it on my bag =D
Hope you like it.
