First, get your washable markers or felt tips of your choice and colour the base of the tin with them.
Next, get your PVA glue and squirt a little on to the base of your tin.
Spread it around by tilting the tin a bit. If you need a bit more glue, add little more not too much!
After you have done this, get your glitter if you are using glitter and poor a bit in. No need for mixing, it will gradually sink in itself.
If you are not using glitter, well then you are done! Just leave it in a quiet place overnight or for two nights, it depends how much glue you added and bravo! In the morning you can peel it out of the tin and use it when reading books!
