2). Adhesive paper (Any stationary shop carries this)
3). Roll of Laminate
Step 2: Print, Laminate, Cut-out!
Using Microsoft Word (The best program to re-size images in my opinion) Insert pictures, as many as you can fit on one sheet using rotate etc.
Once you have as many as you like print them off onto the adhesive paper.
Once that is done I cut out each sticker so they are individual squares. Then take the roll of laminate and cut out the required amount to cover the entire picture.
After its all nice and flat, cut out the sticker edge carefully making it look as nice as you can get it.
