Our family uses these primarily as dishcloths (and as goat udder-washer-uppers), but there's no reason that you couldn't use these as washcloths too. I use 100% cotton, and try to stick to patterns that are simple enough to memorize (no looking back and forth from the pattern to your work all day), and "nubbly" enough to really get in there when you're using these to scrub the holy heck out of something - be it dishes, your face or...goat parts. ;)
This is a fairly new design for me, but it has been selling well, and with the chevron design craze (search chevron on Pinterest and see for yourself) I thought I'd better capitalize on this good thing while I could. But, it'd be rude to keep such a fun and easy knit to myself, so here you go, the Chevrons Dishcloth.
The pattern gets lost a little on variegated yarns, as you can see from my crummy cell phone picture. I'd recommend solids for this pattern.
*Needles: size 7 straight needles (I use a 24" circular needle, so I can smoosh my work into the middle of it when I set it down, as to not drop stitches off the needles. It works!)
*Yarn: 1 ball Kitchen Cotton, such as Sugar 'n Cream or Coolspun Cotton
Cast on 36 sts
Rows 1 & 2 - Knit all sts
Row 3 - K2, *P1, K3* to last 2 sts, K2
Row 4 - K2, *K1, P5, K1, P1* to last 2 sts, K2
Row 5- K2, *K2, P1, K1* to last 2 sts, K2
Row 6- K2, *P2, K1, P1, K1, P3* to last 2 sts, K2
Repeat rows 3-6 until piece reaches desired length, minus 2 rows.
Last 2 rows - Knit all sts
Loosely bind off all sts.
You can eliminate the first two and last two rows of knit sts, as well as the k2 at the beginning and end of each row if you do not want a selvedge edge. I think it makes the cloth look more finished though. ;)
