I have grand ambitions of starting an independent sewing pattern line. I will be specializing in fashionable breastfeeding clothes. The problem is I need a patent before beginning this endeavor (Tim Gunn strongly suggested the patent and I tend to agree with him). Design patents are a lot of money and I don't have that kind of cash lying around ($4,000-$8,000).
An idea I had was to sell patterns that were not nursing wear to earn the money for the patent. Once I obtained the patent I would then sell pattern supplements to convert already-sold patterns into breastfeeding patterns. The non-breastfeeding patterns would be priced a bit lower than the specialized patterns.
Everyone I've talked to IRL say that I should not go forward with this plan since they think I would do best being highly specialized. However, I just don't have the money to obtain a patent at this time. I'm not willing to take out a business loan because I don't believe in debt (except for mortgages).
Any advice? What would you do in this situation?
