1Instructions are for a 6" triangle planter.
Step A: Draw a triangle on the cardboard, and then draw a 5" line from each corner, creating an open square on each side of the triangle. Connect the lines of the open square. You should now have a square at all three sides, which will be the walls of your mold.
Step B: Cut out the entire mold with a X-ACTO knife and ruler. To make perforated lines around the original triangle, cut along the lines but don't cut all the way through the cardboard.
Step C: Turn the cardboard upside down and cover it with packing tape to make the mold easier to remove from the plaster. Stand the squares upright to form a triangular block. Tape at every edge and corner to secure shape.
Step A: Make sure to follow the directions on the plaster of Paris package. Pour about 1" of plaster into the mold, and then put a plastic bottle in the center. Continue to fill mold until you have about ½" or more of space left. Tip: Tap the mold so that the plaster evens out. Let dry.
Step B: Once its completely dry, remove from mold using a X-ACTO knife to cut along the edges of the wall -- the mold should easily come off. Remove the plastic bottle and then use the X-ACTO knife to even out the top surface.
Step A: Draw triangles using a ruler and pencil. We used shades of Green, Blue and Pink to paint triangles on the sides of our planter, but you can create whatever you'd like!
