I hate to waste cupboard space in my bathroom for extra rolls of toilet paper, so I knit-a-net for them. I pulled it up and used a piece of yarn to tie around the top. I used size 15 needles and standard 4-ply yarn for this project.

Here are some other ideas for nets you can knit:

A "hammock" for stuffed animals in a kid's room

A "sling" for plastic grocery bags in the kitchen

A "bag" for rags in the laundry room

A "sash" for a wastebasket.
