Sand and Repaint. Add decals
Denise, here is an idea I thought was so pretty. Perhaps it will helps.
Why not decorate using cut out pictures of toys and Mod Podge (Decoupage).
Here's a post that might help you - https://mycreativedays.porch.com/wooden-toy-box/
Hi Denise, you can repaint the toy box in the colors of your choice and even mask off different areas and use different colors of paint in different areas. You could add more design to it by ModPodging designs on as well. Maybe put some small wheels on the bottom for easy moving around the room if you like.
Paint goes a long way!
Hi Denise, hope this gives you some ideas
Have you thought about chalk painting it? https://lifeonsummerhill.com/how-to-paint-with-chalk-paint/
