So i wanted the most possible blinged out card box without spending a fortune. I finally finished...
Got this off of wedding chicks:
Step 1. After preparing your work area to protect from plaster mishaps, start by inserting the base of your Manzanita tree into the block of foam. Use firm and steady pressure, being careful not to move the branch around. We dont want to make the hole in the foam oversized. 2 or 3 inches ought to be enough. If something goes wrong, you can always turn the foam over and use the other side.
Step 2. Gently lift the and block and branch together, and place it into the container. Use gentle pressure to seat the block snugly down into the container, making sure its level.
Step 3. You can fill the rest of the container with Plaster of Paris, however for this demonstration we rolled up small sections of newspaper and stuffed them neatly around the foam block, leaving about 2 inches of space to the top of the container.
Step 4. Mix your Plaster of Paris according to the instructions on the can. A heavier batch (not too soupy) is easier to work with, and sets faster. Pour the plaster into the container, spreading it evenly over the top of the foam block. Fill to within 1/2 inch of the top. Be advised that a glass container may be a problem, as this material can expand and heat up a bit and could break the glass.
Step 5. Thats it! Set your tree out of the way for about 20 to 30 minutes while the plaster cures. After the plaster has cured, place other materials on top and around the base to conceal the plaster.
