Hey there too-free-spirit-for-this-life ! So nice you want to stop using plastic bags!
If you recycle and compost (PDF file), most household trash is dry and doesn’t need a liner. And when you focus on making smarter purchases, you can reduce waste in the first place.
If you must have a liner, reuse a paper bag. Another solution is to reuse something destined for the landfill (and not recyclable) like a pet food bag.
Do break the bad habit of reusing plastic shopping bags for your garbage. In this case, plastic shopping bags should be recycled and kept out of landfills.
