I've always loved these triangle treat boxes; these are filled with M&Ms!
Measure for any box size where the paper length is twice that of the width; score the long side in half.
My DSP is cut at 3" x 6" and scored in the middle at 3".
Find the midpoint on each of the shorter ends (here, it is at 1.5" on the 3" side of the DSP). Score diagonally down from the mid point to the outer-edge of the horizontally scored line. You'll have two diagonally scored lines from the center point on each of the two shorter sides of the DSP.
Burnish score lines. I used my cropodile to punch ribbon holes on the left and right sides of the top point, before I'd adhered one side of the box closed, with Fast Fuse.
Thanks for looking!
