Whenever I bring a mesh produce bag home from the grocery store, I gather up my half-used bars of soap and make a homemade “soap saver.” These little mesh bundles are great for hand washing and keep soap scraps from dissolving into a puddle.
You can make a soap saver out of any kind of mesh produce bag. Among the many reasons I love to get my produce from local farm CSA’s is I get less packaging, but I do find that I often come home from grocery stores with citrus, avocados, or onions in one of these mesh bags. I don’t save them all, but I do find they can often serve a multi-purpose. The finer and tighter-weave bags are a little softer, but any will work.
Get started making a soap saver. Cut a tube-shaped piece out of a produce bag, large enough to accommodate your soap scrap stash. Tie the mesh off at both ends, trim the ends, and voila! You have a little bundle of soap that will serve you for weeks or months (especially if you place it on a soap dish with drainage).
