This is what you need:
- Mod Podge or PVA
- Acetate (mine is from this pad of fairly thin acetate from back in the day - who remembers overhead projectors? You could use any clear plastic, even old packaging will work I think)
- Paint brush
- Glue Gun
- Scrap paper
- Compass (for drawing a circle not finding your way north!)
However if you put them away carefully in January I think you could get a few years out of them no problem. Ideal if you are one of those people who has a different colour scheme every few years!
