these can be as simple or as intricate as you like. a great use for freebee mousemats
Step 1: What you will need
2. scalpel/exact knife
4. paper (or sticky labels, or even posible to use masking tape)
5. spray glue (not needed if you use one of the pre-glued options)
Step 3: Cut and peel
peel paper away from foam that is to be removed (negative spaces in the stencil, not painted bits)
using your nails or the knife to make a start, carefully pull out the foam from this area, you may have to go over some of your cuts again to make this easier and prevent ripping.
cut the mousemat down to the size of your image, (you can cut the outline with scissors around the shape or do as i have done and leave some excess plastic-peeling away any extra foam)
peel off remaining paper.
Step 4: Paint then print!
press down on paper, fabric or whatever, aplying preasure to get an even print (or roll over it for a good even splat.)
Step 5: Further steps
you could also arrange several of these around a roller (use lint rollers as they come pre-sticky!) for making repeating paterns.
let me know how you get on
