I just finished up this little box to hold 4.25" by 5.5" cards and envelopes and thought I'd share a tutorial for anyone that wants to make one (and for those of you that were lost with my rambling instructions from the last tutorial).
You will need a piece of 7 1/2" by 11" cardstock. First, with the short side at the top, you will score at 3/4" and 6 3/4".
Turn your cardstock so the long side is at the top. Now you will score at 4 1/2", 5 1/4", 9 3/4", and 10 1/2".
Fold your cardstock along all of the score marks. Then, with your scissors, snip along the long side of your paper at each score mark just up to the first vertical score mark. So, you will snip at 4 1/2", 5 1/4", 9 3/4", and 10 1/2" on both the left and right sides of the paper to the first score mark.
You may want to remove the side portions of the top flap so they won't be in the way when the box is closed. I also used my circle punch to punch a half-circle into the box to have easier access to the flap. (See the photo for these two things.)
Now you're ready to assemble your box. I like using double sided tape because I think it holds better than glue.
I use my bone folder to press from the inside against a hard surface to be sure my box sticks together well.
And that's it! Just decorate your box and fill with cards. It holds four 4.25" by 5.5" cards and four A2 envelopes. But you could probably squeeze in six or eight if they weren't too thick.
