2. Fold your circle in half (keep the side of the paper you want to see on the outside).
3. Fold the folded edge up approximately 1 - 1.5cm.
3. Open out the circle and you should have 3 creased lines - smooth out the original centre fold line and stand your half circle up on its base.
4. Pinching the folded edges together, carefully staple each side - this may be a little fiddly to ensure the base of your semi circle stays flat - make sure you push the edge of the original centre crease line up between the folded edges when you staple it
