Five six things I learned this year from Pinterest:
1. Guinea pigs are very photogenic. Their humans dress them up in little Christmas hats and Hallowe'en costumes. Sometimes they even go shopping.
2. If you search for one thing on Pinterest, you will probably get at least twenty more suggested posts on the same subject. You might even end up starting your own board on that subject. It's like giving a mouse a cookie.
3. If you want to travel to a place, someone has probably posted a list of ten free or cheap things to do while you're there. (Eating spicy Thai noodles at the Taj Mahal not included.)
4. Some people pay an awful lot of attention to decorating their powder rooms.
5. About a thousand ways to tie a scarf.
6. Homeschoolers, including Charlotte Mason homeschoolers, make good use of Pinterest boards. I don't have a homeschool or C.M. board at all (I'm retired, that's my excuse), but I appreciate the people who have gone to the trouble of creating them.
