>>6390144I see you have a working hinge on the door! My favorite source for those hinges is Michael's (with 40% off coupon).
As for the egg cartons- you could ask co-workers, family, members of any local clubs you belong to, vendors at farmer's markets to save them for you. I've had success at the farmer's markets. Near closing time, I'd ask for an egg carton, and they'd say, "how many?"
One last hint- you can grout the stones using lightweight spacking paste. Scoop some on a card, add a drop of gray acrylic and mix them. then, use a toothpick to apply the spackling paste and use your fingers to press it in and smooth it.
That's how I got the full grouted stone effect.
