Step 3: Numbers
Catan has number disks which are placed on the board in the same order each game. Each disk has the number (which represents the numbers the dice can roll), dots (to indicate the probability of two dice rolling this number) and a letter (so you know what order to place the disks in).
I actually did the disks last, but it would have been easier to do them first which is why this step is here.
On the flat side of a melting cap I wrote each number with gel food coloring and a walnut pick (I was out of toothpicks). I changed the letters on the top to spell out the message 'Happy Birthday Steve'.
It was helpful for me to have someone reading me the number, number of dots and letter in my message as I decorated so I didn't get confused. Also if you are doing this first you should write down in order each number and its new letter so you can put the cookies in order later.
