Our cheesecloth/muslin drawstring bags are mass produced (in the USA) and are very lightweight (slightly see-through). The 3″ x 4″ and 3″ x 5″ have white stitching at the top with a double yellow drawstring. The 4″ x 6″ and larger have red stitching and a single yellow/orange drawstring. They make excellent cooking, herbal and bath bags, gift bags, potpourri bags, and are nice for storing small items. If you want to use them as culinary or food-type bags, they should be washed first on “gentle” cycle, and it is best to wash them in a mesh type laundry bag to keep them all together and to keep them “safe”.
