Mailbox full of LOVE!

A piece of cardstock 3.5" x 10.5". Score on the long side at 2.5", 5", 7.5" and 10"

I used a rectangle die to create feet, you can use any square or rectangle that fits or even cut freehand.

Here I glued the small tab (the 10" scoreline) inside to create a box. Here you can see the feet as well.
I forgot to take a pic of the 2 circles I cut out of the same cardstock. The circle is a 2 3/8 inch circle that fits on the side of the box. I glued them 1/2 way down to create the curve of the mailbox. 

Here you can see how I glued the 2 circles on the side and attached the tabs.

Here are the 2 tabs, 3.5" x 3/4", scored on the long side at 1/2" and 3", fold and glue inside mailbox.

I started decorating the box with patterned paper cut slightly smaller than the sides of the mailbox to decorate. I also created a small faux "door" using the metallic paper and a small rectangle handle in black. I die cut hearts and envelopes and glued them to clear plastic and then glued to the tabs so the box would look like it was so full it was popping out of the top. Just be sure the pieces are short enough to fit into the envelope when folded, unless you aren't using an envelope. I also diecut the word "love" to attach to the front.

Thank you for looking!
