It starts with a 4 1/2 inch square of paper--you score and punch at 1 1/2 inches, then flip and score and punch at 1 1/2 inches again on the same side. You do this on all 4 sides. The cutting is a tad tricky, but not too hard. I'll try and post a picture of cutting directions tomorrow.
The other box I made is a smaller version of the triangle box that was shown at Leadership this year (I saw it on the live feed). I found the directions for the smaller version here on Mary Brown's blog. This is my first try at this box--there are some things I would change, but it is really cute and it holds more than you'd think (unlike the above box which holds about 3 kisses). The original was designed by Pootles, I believe.
