Dyeing is a creative way to use leftover pieces of wood to make toys such as colored stacking blocks for a child, picture frames or even wooden beads for jewelry-making. You can use wood dye, which is manufactured in many different colors, but food color is both bright and non-toxic, making it perfect for objects that are going to be in contact with food or children. Using food color may not create as long-term a finish as a chemical colorant, but it's safer.
Prepare Your Wood
Sand your pieces carefully to ensure the edges are entirely smooth. Rinse off the dust and let your pieces dry thoroughly before proceeding.
Stir a few drops of food color into 1/4 cup of warm water. Add 1 tablespoon of vinegar and mix. Adjust the amount of food color until the water is the desired shade; more food color will make a darker stain.
Place the wood-and-dye solution into a 1-gallon zippered bag; let it soak for at least a minute and longer if you want a darker stain.
Remove the wood pieces from the dye and allow them to dry completely. Paint the finished pieces with a food-safe wood finish to protect the dye.
