The box I used was designed especially for this project by Steve Harvey Miniatures. It's beautifully made right here in America. I have seen much smaller boxes hand made for the price of this one. Your hard work on this box will last generations. Last I checked it was $32.50 including shipping. There will be other design themes for this box in the coming year. I have a Halloween theme that is hilarious.
An important element of this project is a stamp called “arch element” made by Stamp Francisco. If you like architectural style boxes, this stamp will get a LOT of use. They have a super website.. Stamping on card stock will raise it a little above the background which is my own variation on decoupage.This stamp is $8.99 mounted, or $5.39 unmounted. It's a workhorse for any kind of box project. Miniature buildings are popular right now, too.
Here is where I sing the praises of Dover Books. Without them much of the older visual ephemera of our world would be lost. They are a public service, and I still mourn the day they closed their New York City store. I have depended on them for instruction, magnificent images, and re-issuing out of print books all through my art career.
