You receive in each kit:
A pre-numbered printed board
A brush
Paints
Full instructions
Of course, the contents will differ for each type of Art by Numbersthat you do.

Additional materials you will need are:
1 - Clean water for rinsing off the brush.
2 - A mixing pallette for mixing colours. The instructions on the board will tell you what colours you need to mix together like this: 43 over 56. So you will need to mix those two colours together to achieve the correct colour for the painting.
3 - A clean cloth just in case you make a mistake.

One thing I have bought recently is a small table top easel to make it easier for me to paint. The easel was in a sale and I managed to pick it up for £5, a saving of £10.

Well worth the purchase!
