I love Pinterest and have thousands of pins. It used to be so much better... before they started sticking ads and clickbait in among the pins. I hate that and don't spend nearly as much time browsing as I used to, because of that garbage.
I love to look at what other quilters have pinned... and yes it can really suck you down the rabbit hole. It's not a pattern site. Sometimes there is a link to a pattern or blog tute, but not always. But you have a picture, and if you can create without a pattern, you can take it from there.
