So if you don't mind answering a logistical question, how does that work? Let's say that as a stretch goal we offer a custom miniature (or a tarot deck or whatever). We wrote the book, we work with the printer, we can handle shipping etc, but we have to outsource physically creating the miniature/cards.
What is your strategy for not letting that stretch goal hold up the main product in such a situation? Do you just not offer bits that you and your team doesn't create itself? I'm having trouble seeing how delays can be avoided in any area where parts of the rewards are outsourced, especially if you want to keep costs down by making one shipment instead of several.
Am I looking at it the wrong way, or asking the wrong question here? As someone in the early stages of planning a crowdfunding campaign, I'm grateful for any pointers you have.
