I tried acrylic craft paint on walls and had a terrible time removing it later. So I looked into it found that that Martha Stewart recommends using latex wall paint for stamping on walls. Latex paint is actually a type of acrylic paint, so I can see why that would be confusing. Here is the Martha link if anyone needs it:

Paint the paint onto the stamp - dipping it in the paint gives you too much paint. Maybe use a sponge brush and just paint it on the stamp. I've also heard a suggestion of taking a piece of felt and putting it on a styrofoam plate, then adding some paint to it - to make a paint pad basically.
