I needed a quick, easy, and cheap way to cover my small blueberry bushes to keep them safe from birds. Big rolls of netting and such are annoying to work with. The "bag" type for trees and bushes aren't cheap (not expensive but I've spent my gardening budget for the year). Turns out that mosquito nets for hats work well. You can cinch them tight around the pot. I believe they'd work well for other things too.
A 2 pack was around $6 on Amazon.
