Dishcloths make perfect travel knitting. The patterns aren't too complex, and it doesn't take too long to finish. They are also a good place to try out new stitch patterns.
This one is a variation on Grandma's Favorite Dishcloth. It does require a bit of concentration though. (Ask me how I know.....)
This one is a fun variation on the basket weave.
And these two are Mere's favorite wash cloth pattern. Something happened this time, and the first one turned out a bit wonky, more lack of concentration, probably, but the second one is just fine.
This pattern is called Stacatto and was from the KnitPicks site.
This is a fun stitch called the waffle stitch and is interesting on both sides.
Links to all of these patterns can be found on my Ravelry page: jatshaw. Try one; they are fun! To see what others have on their needles go to Patchwork Times.
