I print out my partner's questionnaire and highlight what stands out to me, like if it says I hate spiders or I love miniatures. I start making a list of what interests me and is within my capabilities. That list evolves over time until I get it down to 13 ideas. This really helps me with a craft store shopping list which I really need because the closest one is over an hour away. As I finish a project I mark it off. My final list puts the items in the order I'd like them opened. I love your idea of a secret Pinterest board!
Have you tried asking the person who posted it where it's from? If you can locate the post that interests you, you can either ask in that thread, or send the original poster a private message. Good luck!
