What does everyone use to stain or filter their milk? I am currently using a coffee filter in a funnel and it is so SLOW. I am milking 2 Mini LaManchas, both of which have twins still on them. I am not separating the babies at night yet so I am only getting about 2 cups a day and it takes 45 minutes to filter those 2 measly cups. So, what does everyone else do? Thanks.
