I'm throwing in some dishcloth photos.
This one is done by playing with the varigation in the yarn. The yarn is two-colored and one color is knitted on front and purled on back and the other is purled on front and knitted in back. Super easy pattern but unique results. The pattern depends on how many stitches you cast on and of course I forgot how many I cast on. My best guess is 39 sts on 4.5 mm (size7) needles.
I stopped doing the Monthly Dishcloth KAL a while back but am back on the wagon. The mid-March cloth was based on illusion knitting technique, where you alternate knitting and purling with two colors to come up with a pattern which appears at a certain angle. Look.
I made that cloth with Knitpick's CotLin which is a super soft cotton (tanquis), linen blend. I want to make a top out of this yarn. It's really nice. Those two colors go very well together.
