You will need:

• paper
• colouring media - pencils, pens, inks, watercolours, etc.
• access to a list of colour names (art supply site, Freetone, a palette maker tool, etc. just for some inspiration)

Do:

• Create a grid with a square for each letter of your first name, or your whole name, if you're inclined.
• Choose a colouring media of whatever type you like, and for each square in your grid, colour it with a colour that starts with the same letter as that letter of your name. For example: Lemon, Orange, Naples Yellow, Indanthrone Blue, Tangerine, Alizarin Crimson.

Notes:

• If you're going to use watercolour paints as your colouring media, make sure you use watercolour paper as your substrate. Make sure to use bleedproof or marker paper for markers.
• You don't have to arrange your squares in a square grid, you can do whatever shape you like, or no shape at all.
• Do this any size you like. A large one would make for an interesting bit of wall decor. Might make for a nice gift too.
• You could also use this as a way to decorate a journal or scrapbook cover.
• Don't put the letters in the box, just colour the boxes.
