Same with this picture.
Do you see the T-pin that holds the plate rack up? They come in different sizes. Just use a small one for the lightweight things and larger for heavy items. I learned about these at a Home Interior party and I think the consultant said the biggest one holds something like 15 pounds!
If you make a mistake when hanging something, don't worry they only leave a small pin hole in your walls. They are w-o-n-d-e-r-f-u-l. You too will heart T-pins. P.S. I FORGOT TO TELL YOU I HAVE NEVER PUT A T-PIN IN A STUD. IT MAY BREAK BECAUSE THEY AREN'T AS THICK AS A NAIL. I JUST PUT IT DIRECTLY INTO THE DRYWALL AND THEY WORK FINE.
