When it comes to markers and bleeding, there are a few things you can do to help keep the ink where it belongs. For one, make sure to use a fine-tip marker. These have less ink flow and are less likely to bleed through your paper or project. Another helpful tip is to apply a light layer of clear gesso or Mod Podge over your wood before coloring. This will create a barrier between the wood and the ink, helping to prevent bleed-through. Finally, be sure to color in small sections at a time, going back over each area with multiple layers of color until you’re happy with the result. By following these tips, you should be able to avoid any bleed-through issues when coloring on wood!
