I am not a model...so don't laugh at me! And I'm representing the team!:)
Here are the steps I took.
Mix Martha Stewart Any Surface paint with fabric medium.
Stamp a random piece of denim or fabric
to get the pressure right for the stamp.
Begin stamping your pattern on the jeans.
You may need to allow dry time between
stamps and front and back of the legs.
When through and after dry for about 24 hrs., run the iron over your jeans to set the paint.
Wash them with no fabric softner and the color should set into the denim and make them look like you bought them that way!
