Here’s a way to cut back on using plastic: make some reusable bowl covers.
Re-Nest has a how-to on creating your own bowl covers with cotton laminate/oilcloth and elastic. The resulting covers can be washed and re-used as much as you want, thus reducing the amount of saran wrap you use in the kitchen. Along with being environmentally friendly, that will save you money in the long run.
Of course, I’m not convinced these covers can completely eliminate saran wrap–they aren’t going to keep air out of your food as well as plastic can, and so may not be ideal for all situations. However, for general food saving, reusable bowl covers are a great idea.
