Gee, I'm glad you guys are amused. But the fact is, diapers make one of the most useful kitchen cloths available.
I use them to strain stock, as mentioned (even for a few quarts, btw). But also as a general wipe-down cloth and hand towel.
I buy them new, give them a wash to get rid of the sizing, and voila! They're relatively inexpensive, reusable, versatile, and last two-days longer than forever.
They have taken the oath of the brother in blood, in leavened bread and salt. Rudyard Kipling
