Licensing my design

I am a furniture designer. I want to license my design to my friend’s store. What do I have to do legally to make this happen? What other steps would you recommend?

I think you might want to pose this question on the Furniture World Magazines trade board:

I think you will probably get a better response there as that board is much more business oriented and specific to the furniture industry.
