Good for you!
I do what you do. I also take my own bags to the grocery store, department store, etc. Yes, plastic can be recycled, but there is a cost to the environment in producing them. I find the canvas bags hold more, break less often, and don't tip over in the car as easily.
I use see-through mesh bags for produce purchases - you can buy them in the grocery section, but a friend of mine used old sheer curtain fabric to make some. You can use a drawstring or just a twisty-tie. They are see-through so the cashier can easily see the label with the PLU number on it.
I find most things that say "dry clean" can be hand washed or washed on gentle cycle.
I use baking soda to clean my formica counters, the porcelain sink and the bathroom.
I don't use paper towels - I use the washable, reusable cellulose wipes or the cloths, and put them through the washing machine every week. I don't use paper napkins - again, I use cloth. They take up virtually no room in the washing machine so it's not like I'm running extra loads.
I open my dishwasher after the rinse cycle, pull the racks out, and let the dishes air dry. It adds moisture to the air (especially important during dry winters) and saves a ton of electricity.
I line dry my delicates on a drying rack - saves drying time and makes bras and panties last a lot longer. If I don't feel like setting up the drying rack or don't have a lot of stuff, I just clip two items to every skirt hanger, and hang a third item around the hanger hook - then they just hang in the laundry room and dry overnight.
I have at least one yard sale every year. You'd be amazed what people will buy. I also have a "free" area for stuff I think has no value (or hasn't sold in prior yard sales) - somebody always takes most of it! We also have neighborhood yard sales to get several families involved and increase the traffic - and the neighborhood kids usually scoot from one sale to another, claiming things for free or for ten cents.
I compost - a lot. I keep a plastic container on the kitchen counter for food waste: vegetable trimmings or leftovers that are no longer edible, the stuff I find at the back of the fridge that's, um..., past its date, stale crackers or bread, egg shells, coffee grounds, etc. - anything but meat, citrus and heavy oils. When the container is full, it goes out into the compost bin. I add grass clippings and raked leaves, any old soil from potted plants that have been transplanted, trimmings from house plants, etc. Anything big I cut up into smaller pieces - bananas peels, melon rinds, etc.
To start it, I threw in a few shovelfuls of dirt from the woods to be sure there are worms, microbes, and other things necessary for decomposition. Every so often I turn it and stir it a little - that circulates everything, and gets the earthworms working throughout the pile to break everything down. It provides so much extra soil for gardening. Moreover, it significantly reduces waste. I even do this through the winter. If it's really cold or snowy and I don't feel like going to the compost bin, I just stack the full containers in the garage so they're out of the house, and when we get a mild day, I take it all out at once.
My neighbors have a couple of rain barrels attached to their downspouts - you can get them in garden centers and through gardeners' catalogs. Then they collect rain water for water plants and shrubs, reducing their water bill substantially. There's even a spigot for attaching the hose. They float a little canola oil on the top to prevent mosquitos from laying eggs. That's next on my list.
