Before doing anything with the wood, you should have a suitable place to work in, where you can make a mess and it doesn't matter. Use a table or other surface that is comfortable to work on and that you’re okay getting a splash of dye on. Cover it with a plastic cloth or some other protective surface. You'll probably want to put on an old t-shirt and some plastic or rubber gloves, too. With rubber gloves on to prevent staining your hands and fingers, add a package of drink powder to water to create a dye. Adjust your ratio of water to powder until you get the shade that you want.  Cherry drink powder will come out red, grape will come out purple, etc. If you want a darker, deeper shade, just add less water. You can also combine colors (red and yellow make orange, for example) if the color you want is unavailable in flavor form. The best perk of using drink powder as your dye? It smells delicious. Using a foam brush, spread the paint everywhere on the wood, wherever you need the dye to be applied. It will soak right in and smell fruity too. Remember that it will get lighter as it dries, so wait a minute to see if you need to apply another coat or two. You'll probably need a couple of layers, so be patient. Be sure to coat the entirety of the wood before you move onto coating it a second time to keep the color even. Wait for 16-20 minutes after you have finished spreading the dye. This will give the dye time to soak into the wood. Then, put the drying wood in a sunny or windy place to dry quickly. When that time is up, your art is ready. Check the color. When the wood dries completely, see if the color is dark enough for your liking. If it isn't dark enough, dye the wood again.
Set up your workspace. Prepare the drink powder. Paint the dye onto the wood. Let the wood dry.
