A letter box is perfect for storing important notes, letters, bills and more. This box is made of card, which is a great surface for painting. Apply tape where the colours meet to prevent them from blending together; we recommend using paper tape. It is easy to remove without damaging the box if you take it off immediately after painting. We painted the letter box and letters with Hobbylack. Attach letters, flowers and a butterfly to the box with glue after the paint has dried.
