Use a Piece of Fabric as a Bowl Cover
Don’t feel you need to go out and buy new fabric either; look around your house and you might find a spare tea towel or pillowcase; a quilted placemat makes for a great insulated version and even a vintage handkerchief can get new life as a festive party bowl cover.
If you’re not as into sewing, you can scale back easily to a barebones DIY approach by simply draping a tea towel or handkerchief over a bowl and secure it in place using a large rubber band or even one of those brightly-colored elastic headbands.
Use Plastic You Already Have
If you’re really concerned about your bowled food being air-tight, take the outer bread bag from a recently-finished loaf of bread, cut it open along one side seam and across the bottom so it opens into a flat sheet of plastic and use that to over your bowl; it was unfortunately headed into the trash anyway, so give it a few more chances to serve some purpose since you already have it.
DIY Reusable Snack Bags
Similarly, you can find a lot of DIY sewing alternatives for plastic snack and sandwich bags. Rolling down a small fabric (or even brown paper or wax paper) sack and securing it shut with a couple of binder clips can be your best friend, if sewing velcro or drawstring pouches ain’t your bag (oh yes, you saw what I did there).
DIY Beeswax Wrappers
I’ll be the first one to say I don’t have enough time in the day, but you can even make your own beeswax sandwich wrappers from scratch if you want to get all crazy. If you prefer to slow your roll, old-school bandanas and an appreciation for the art of furoshiki can yield you good snack packages too, while honing your knot-appreciation skills. If you are concerned about longer-term freshness of your sandwiches and snacks (I dunno, personally, I just eat faster), you can find laminated cotton fabrics that are PVC free, BPA free, lead and phthalate free out on the market.
Reuse, Reuse, Reuse
Or, if you were like me growing up, all my sandwiches were neatly folded up in crisp wax paper and I’d bring that paper home each day for reuse until the relentless onslaught of my sandwich’s tomatoes finally made the wax paper shout for mercy by week’s end; that not only gives good mileage to your reusing efforts, but if you have kids, it also teaches them about the responsibility and importance of using and reusing what you have.
