DISHCLOTHS or WASHCLOTHS whichever you prefer ;))
Standard Machine (4.5 mm) (I knit mine on a Studio 580 electronic)
I used leftover crochet cotton for my dishcloths. In particular South Maid, 100% Mercerized Cotton (economy ball) and I found that T7 was perfect.
Cast on 35 - 0 - 35 with a crochet cast on (remember not to get it too tight!)
Knit 2 rows of stocking stitch and set machine for pattern. I used Card #1, Pattern 5 on my Studio 580 electronic, and tuck stitch. On the Studio SK360 card 7A is the same or use card #1 and put on the double length lever. (If you have an SK700 or an older punchcard you should have a similar card for card #1. Just look for the card that has a oxoxoxoxo across the first row and every row thereafter, with the holes alternating on each row - put that card in and use the double length lever.)
RC000. Knit 2 rows in the tuck stitch pattern and then stop and hang claw weights evenly across the row. (I have more than one machine so I was able to hang 6 claw weights. If you have a lace carriage you might try those weights.) Knit until you have 150 rows. Cancel pattern and knit 2 rows of stocking stitch. Cast off. And that's it. Makes approximately a 12 inch by 12 inch square.
Chunky Machine (9 mm)
I used leftover Sugar and Cream (balls) and Bernat Handicrafter Cotton (4 ply Worsted Weight - on cone) for my chunky dishcloths. I have a Brother 260 chunky machine at the moment so I used that.
Cast on 17 - 0 - 16 with a crochet cast on. Set machine for T8 (or whatever works for you). I used Card 8 in tuck. Knit 4 rows in garter stitch (use your garter bar for this - I used the one from my standard machine). Knit 50 rows in pattern and then knit 4 rows in garter stitch again. Cast off loosely. I also tried using card #2 but it was harder to knit with this cotton than Card #8. Hey, they're dishcloths, you can do anything you like!!
