I hate stuff falling into the milk. Don't have time to sew or I'd make some round covers with elastic in the hems. So I cut some muslin squares, about 6 inches wider than the top of the milk bucket. Then I tied a knot in each corner and pulled it over the top of the bucket, making a bowl shape depression in the center. If the cover is taut, the milk tends to spray off it, the depression keeps it from being so messy. Takes just a couple of minutes to make one. I have several now, and lay them on the washing machine to dry between loads of wash (so they don't lay around wet and get sour). I put them thru the dryer after washing.
