Teddy Talk: Creating, Collecting, Connecting

Hi everyone!

I'm looking to create a business around soft toys, however I am not creatively minded when it comes to design and pattern production so I would be looking for assistance with this.

Has anyone ever sold a pattern of theirs for exclusive use by a company/signed over their rights as the designer to a company who then went on to sell a product with their design?

Very much in the early stages of planning but would love to get as much insight as I can from anyone who may have any experiences with this on how they went about it, contracts etc.

Thanks in advance,
Brooke.
