I'm in love with Pinterest. I've tried a lot of different things.
1) Fitness area gives me tons of motivation and ideas on how to change up my workout routine.
2) Recipes have been hit and miss. Some amazing, some a failure. Overall, more good than bad though.
3) Home decor ideas have rocked.
4) I've made several of the crafts and all of them come out looking pretty awesome. I now make the oversized ruler growth charts and they look amazing! I've also made a tent/fort out of pvc pipe for my boys and several other crafts.
5) Tried several of the hairstyles. Some look awesome. Some didn't work on my hair at all.
6) Tried some of the cleaning products. A shower cleaner was exciting because it was the fastest and easiest shower cleaning in my life. It made me want to show all guests my showers/tubs before any other part of my home. Also, a pin for cleaning the outside windows was wonderful too. Easy and the results were breathtaking.
All in all, I've had more good experiences than bad on Pinterest. Now my hubby knows that whenever I say, "I saw this on Pinterest....", he's got a project in his immediate future. He's not complaining though, because he's loved the results too.
Good luck!
