Make your own market bags and do the planet a favor and stop using plastic.
Fabric bags are also a lot stronger.
Your own bags can be simple or fancy and will last for years.
I suggest you use a heavier weight cotton twill or canvas. 1 yard will give you 2 bags.
I am working on ready to print panels for market bags with a variety of prints to add some color to your life.
