I have just bought a secondhand wooden train set, it looked lovely in the photos but now that I have it I can see that it is really, really well loved! It is very chipped and I had wanted to give it to DD for her birthday but I feel a bit mean as it does look a little worse for wear though I don't suppose she would really care. I am thinking maybe I could try and re-paint some of the pieces to brighten it up again? Would I need to sand it all down first, and then apply some non toxic paint? I have found a set of acrylic paints on amazon but no idea if they are non toxic. Anyone done anything similar?
