We used a dark stain and a lighter coat on top to give it a multilayer stain.
Wood putty can be applied if there are any noticeable gaps on your parts. Apply in and around the gaps and then sand to blend into the material.
Use a stick help stir the can of stain and use a cloth to apply a textured stroke to add those wood grain patterns.
Don’t apply a lot of pressure, just gently glide the cloth across parts. Fold the cloth into a small shape that can fit around smaller pieces.
Allow the stain to dry and the use the 220 grit paper to remove any excess colors. The remaining stains between layer will give it a wreathed look.
