Transferring pictures to tiles by using Nail Polish Remover. This is freaking ingenious! (How about using these as drink coasters for your coffee table, I wonder if the sweat from the glasses would ruin it though) LOVE IT!
I would recommend doing it outside as it stinks and the rust from the steel wool will stain concrete so do it in a shop or over the road. DIY Vintage Wood Stain look. (How to age new wood). Good for all things wood!
