I want to make a bracelet with the word 4df-990 but i dont know how to....

You will have to use the alpha generator in this case. you have to build your word out of characters.
If you look at what is already in the text box, you will see that the B's spell out ALPHA. Use letters B-Z to spell out your word. For an example, I made the number 4 for you. It's just a basic 4 nothing fancy. I hope this helps you some.
------
-B--B-
-B--B-
-BBBB-
----B-
----B-

All lines in your pattern must have the same number of characters. The first line has 6 hyphens, which means, every line after that must have a combination of letters and hyphens to equal 6.
