1. Get a piece of cardboard
2. Measure 2 cm from left edge. Make a line. Measure 12 cm from line. Make another line. Measure 2 cm from last line and mark. Measure 2 cm from bottom edge. Make a line. Measure 8 cm from line. Make another line. Measure 2cm from last line and mark. Measure another 8 cm from the last line. Mark and finally measure 2 cm from last line and mark.
3. This is a dollar store seam ripper used in sewing. I find it works perfect to lightly score the cardboard so that it will bend in a clean line.
4. Place a ruler alone each line and lightly score. Place the seam ripper at an angle and pull towards you. I use the same amount of pressure I would use with a pencil when drawing. Go over each line 3 or 4 times. If the cardboard is very thick use more pressure. If you use too much pressure you will actually cut through the carboard.
5. Use something hard and smooth to flatten the edges. Scissor handles work perfectly!
6. Paint the box. I used acrylic paint for this box. Let dry completely.
7. Make cuts as shown.
8. Fold up the sides and front of the box. Fold over the tabs from the sides and glue to the front of the box.
9. Bring the lid of the box up and re-fold at all folds.
10. Finished box.
This technique works perfect for any size of box. It will also work with heavy card stock or watercolor paper.
