Plaster of Paris handprints make thoughtful, personalised gifts for parents and grandparents alike. You can purchase handprint-making kits from a craft store to make your own plaster of Paris handprints, but these kits can be expensive. The other option is to make your own using plaster of Paris and a disposable pie plate.
Mix the plaster of Paris according to package instructions. Mix enough to fill the inside of a disposable pie plate. The prepared plaster of Paris should have a thick consistency that is sticky to the touch.
Pour the mixed plaster of Paris into a disposable pie plate. You want a minimum of three-quarters of an inch in the bottom of the pan.
Press your hand, or your child's hand, into the centre of the pie plate, firmly enough to leave an impression but not so deeply it goes through to the bottom of the pie plate. Remove the hand from the plaster of Paris and wash it thoroughly under warm running water using soap. Although plaster of Paris is safe, prolonged exposure can irritate the skin and cause a burning sensation, especially if the skin is question is sensitive.
Allow the plaster of Paris to dry for 20 minutes. Press the end of a drinking straw into the top centre of it. This will leave a hole when it dries so you have a way to hang your finished project.
Allow the plaster of Paris to dry for a full 24 hours. Remove the drinking straw.
Decorate the dried handprint. You can paint the entire thing solid colours or add designs to it. Include your name (or your child's name) and the date on the mould somewhere so you can remember when it was made.
Insert a piece of yarn through the hole the drinking straw left and tie the ends together. Use the yarn to hang your finished handprint.
You can remove the plaster from the pie plate after 20 minutes if you want, but it will still need to dry for a full 24 hours. Another way to decorate the handprint is to insert coloured stones or glass beads into the plaster before it dries. Instead of hanging the completed handprint, you can also use it as a trivet or garden decoration.
When preparing the plaster of Paris, use caution. Wear rubber gloves to keep it off of your skin. Also avoid breathing in the dust. If necessary, use a face mask or tie a bandanna around your face to prevent this.
