I've got my knitted dishcloth linked to my ravelry profile, so now I can easily add any more patterns I come up with! Here's the crocheted version of the dishcloth Mom taught me.
Worsted weight cotton yarn
Size F (3.75 mm) or G (4.0 mm) hook
Skill level: Easy
chain 35. dc in each chain until you reach the end of the row. ch 2. turn.
dc in every dc, chaining 2 at the end of each row before turning.
continue this for 10 rows.
If you want to make the dishcloth bigger, simply add more rows.
If you make this pattern, let me know! I'd love to see what you come up with.
