Floral frogs are devices, usually made of metal, clear glass or acrylic that are used to hold the individual flowers of an arrangement in place. Since the advent and increased popularity of florist's foam, reusable floral frogs may have become harder to locate. These devices can also be misplaced or accidentally thrown away. However, a disposable floral frog can be engineered quickly using a few common household items.
Cut the bottom inch or so off a disposable paper cup. Save the bottom part and discard the upper portion. A cup with a slight ridge at the bottom works best, as it will be better able to hold weighting stones on its upper surface.
Push toothpicks or stickpins through the cut bottom portion of the cup. If using toothpicks, push them through from the cup bottom, which is formerly the side of the cup that would face down if it were filled with water. Pushing the toothpicks through from this direction will ensure that they maintain a sharp tip. If using stick pins, push them through from the other side, which was formerly the cup's interior.
Place this makeshift floral frog in the base of the container where it will be used. The sharp ends of the toothpicks or pins and the cup bottom should be facing upwards.
Trim the bottom of the toothpicks if they are too long and seem unstable. Be sure to cut the bottom of the toothpicks rather than the top so that the sharp ends are maintained.
Arrange decorative stones or rocks on top of the cup bottom or pile the rocks around the whole device to hide the cup and weigh it down.
Place flowers on the floral frog as with a regular, reusable frog.
