Another tip, that I use that may help a few members.
For small items such as Xmas Tree Decos, or small sections of an item that requires a bit of colour, I use Nail Polish, What's left after I do my nails
There are some fantastic metallics and glitters available in nail polish and if you go to the discount shops you can pick up pots from 50c each.
Another good source is chemist shops when they are getting rid of unwanted stock and have a tub full discounted. If the polish is a bit thick a few drops of lacquer thinner fixes that.
