I have used this cloth for several things, all with great success. First, I cut pieces to cover the lids of my kefir, buttermilk and sour cream, and yogurt jars. Then I cut pieces large enough to hold scraps of vegetables that I saved while cooking so that I could boil the in a pressure cooker to make chicken or vegetable broth and then emptied the bags into the trash but kept the bags I had opened and washed. They worked perfectly for every task. This is very good quality, and I highly recommend it.
