Doesn't look familiar to me either for tutorials. When I can't remember I try to remember anything about the time, roughly when I got something. Try trying to figure out in general when you might of purchased it, check order history if needed. Then think about any invents like new babies, etc... or simply missing someone and wanting to make something for them to send.
If nothing else, set it to the side where you can look at it to see if it can jog your memory, and if all else fails, make into something that you are inspired to do so.
