- Square of cardstock (any size, the finished box will end up 25% of the diagonal measurement)
- Pencil and ruler
- Folding bone
Any sized paper can be used as long as it is a square. The finished box will always end up a quarter of the size of the original square when measured from corner to corner.
Take any size square of paper or cardstock. Draw two lines diagonally from corner to corner. This will form a large X, marking the center of the square. Don´t worry about marking the paper as the marks will be on the inside and therefore will not be seen.
Tip: Practice on scrap paper and keep any finished boxes to try different rubber stamp positioning and techniques.
