- Draw on the canvas by clicking and dragging on the white squares - You can drag the colours slider to change the colour - You can change how big the grid is by dragging the Grid Size slider up or down - You have to triple click a command and then do CTRL + C to copy it, then go back into minecraft and do CTRL + V to paste the command in. Repeat this until you have pasted in all of the commands.
