The first Pinspiration is for all those pesky tank tops and shirts that are always falling off the hangers without special hooks built in. Just add a little hot glue to the ends of the hanger, let dry, and Ta-Da! No more clothes falling on the closet floor.
The next DIY handy pin I tried was using acrylic-latex caulk on the bottom side of a rug to keep it from sliding around.
I was really excited to try this pin because I have a few rugs that move around a lot and I'm too cheap to buy the rug-gripper-thingys (this is the technical name). But to my dismay this Pin was a fail. I had a test rug and I did the vertical lines every 2-inches, let dry and it slid more on my tile than it did before I used the caulk. I also tried diagonal lines on a rug that slid everywhere and again, no luck.
I would have had more luck with this pin if I would have just caulked my rug to the floor, as apposed to letting it dry. Maybe you have to have special floors for this pin to work. Until I have those fancy floors, I am going to chalk this up as a Pinterest Fail.
