For those that may not know, Pinterest is a free website and app that allows you to quickly capture and organize images from the web (or your own pictures). I use it a lot to collect ideas for my layout or modeling projects. When I am surfing the web, if I find a picture I like, I just click the "Pin it" button on my toolbar and it will display all the pictures on the page. I select the picture and then pick which of my "boards" (think bulletin boards) to save it on, and, voila, the picture is added. When you are viewing the board, you can click on the picture to link back to the original site.
You can also search Pinterest for topics and "follow" other people's boards, and even pin their pictures to your boards. Pinterest use is about 98% women -- they use for their fashion, beauty and decorating ideas. But it works well for any hobby.
Here are a few links to some of my boards:
1. Hiawatha I created this one when I started collecting Hiawatha passenger trains. It helped me to compare the offerings from different manufacturers, as well as prototype photos.
2. Train Stations I used this one to collect ideas when I did a kitbash of 3 MTH Bank buildings into a grand station. Some of the pictures are from OGR Forum members.
