First and foremost, congratulations on a wonderful piece of art. The realities of accounting should not distract you from the fact that the project was a success and enriched people's lives.

Although you paint a pretty bleak picture of the finances, as others have pointed out above, this does not reflect the economic reality.

The typo impacted your profit margin significantly - without it, you would have had an additional $7k and a margin of 19%.

But this is only a side show. Even if you had made 0% on the posters shipped to the Kickstarter backers, the 800 posters remaining represent a book value of $96k. (Less a few hundred dollars for storage).

Assuming you can sell at this price, your three years work will be amply remunerated for a part-time project.

In the end, Kickstarter functioned as it should. It reduced your risk by providing a pool of known buyers and left you with the infrastructure for approaching your market. That market is your final reward.
