Use only 100% cotton yarn and a #9(I) hook.
Chain 35 stitches loosely. Hdc in 3rd ch from hook and across.
*Turn and ch 3, dbl crochet in back loop only across.*
Continue from * to * until you have 14 rows.
Turn and ch 2, hdc across and fasten off.
(Going into back loop only forms a ridge across each row,
the better to wash that egg off the plate.)
If you buy the cones rather than the balls, you can make 8 or 9
cloths from each cone.
