I would like to design a tartan to commemorate my upcoming nuptials. I would then like to have a kilt and some other items made. I'd like it to be heavy weight pure new wool. Knowing that it will take some time to do the job in full I'd like to start soon as we are tying the knot when I get home from deployment.

What is the first step that I need to take?
What are the necessary succeeding steps to take?

Thank you very much, friends, for your wealth of advice.
