If you like to cook, check out this website (and find others) for Cooking on A Budget Or go through your cupboards and organize things, then go online and find some recipes that utilize what you’ve already got.
Make a list of 10 walking friendly places that you would like to visit, that you either have never been or haven’t been in a long time. Lakes, streams and ponds are always my favorite places, and of course any kind of forested area.
If you have a camera, start making really good use of it. Is there a subject that pleases you? Maybe it’s landscapes, flowers, patterns in nature or architecture, alleyways, mushrooms, insects, stuff you find on the ground, whatever, then start photographing.
Most museums have a free day, once a month, and if the museums are near each other, they will likely have the free day for each one, be on a separate day (so you’ll come back).
Start clipping coupons, and only clip coupons for stuff you actually use, then organize them according to due date and type of product. And check your the coupons and ads and free entertainment mags for half price restaurant coupons.
The free entertainment guides will also list all sorts of things from free outdoor movies, to chili cookoffs to organ concerts and kid’s dance recitals and plays. Sometimes there are free outdoor, holiday related band concerts and crafts fairs, and sometimes you can get into some of the holiday events for the cost of a donated can of food, like the ice rink or a holiday music production, or sporting event. Find out if there will be any Fall Festival or Halloween Carnivals in your area, those are usually free and fun for people watching, and you might just be able to afford to buy a brownie or a piece of fudge : )
This might be something that is only fun for me and my best friend, but we like to go down to our local Asian grocery store (with a camera) and take pictures and notes of the names of the produce, then we go home and look up recipes online to make with all of the nifty things we find. We’re both photographers and cooks, so this activity kills two birds with one stone. I have some of the lovliest photos of produce now!
The local library almost always has some kind of free activity going on, whether it’s a movie, a lecture, a class or a concert. Check their schedule.
Start early on making some homemade Christmas cards and/or decorations. I love to make potato prints! Maybe go leaf hunting and then dry the leaves.
Some fabric or yarn stores hold free sewing and knitting classes.
Learn to give really good, stress busting Facial Massages and Foot Massages to each other.
