Using your unfinished wood horseshoe shamrock shape is easy. First, peel off the protective paper backing. This will give you a clean surface to work with. You can use it for all sorts of crafts, like painting, adding decorative elements, or even using it as a base for a wall hanging. If you've asked for a hole, make sure it fits your project's needs. When it comes to maintenance, keep it in a dry place to prevent warping. If you paint it, use a sealant to make the paint last longer. Always handle it gently to avoid chipping the edges. If you have any other questions or run into issues, don't hesitate to message the seller.
