Envelope Template

After some experimentation, I hit upon an envelope for 3 x 3 cards that I like..they are not perfectly square, which is nice in case your card has bling or dimension.

First, you'll need an 8" x 8" piece of paper (which will make 2 envelopes.  Cut in half so you have 2-4"x8" pieces of paper.  Put one aside.

Score 3/8" along each long edge as shown in photo below:

Turn the paper the the other way and score at 2" and 5.25".  Cut out the pink areas as shown in the diagram below.  You can use a corner rounder on the top and bottom flaps.  Fold in the side flaps.  Apply glue as show in diagram and fold up the bottom flap.  Voila!  Really cute envelope!
