The Woven Waves Dish Towel from Nich Knits uses slipped stitches to make a fun textured pattern that looks more complicated than it is but can totally be worked by new knitters.
Oh La Lana Designs has a great set of dishcloth knitting patterns that uses only knits and purls, so it’s great for newer knitters who want to try out some new stitch patterns. The little diamonds in particular are a lot of fun and add scrubbing power.
The Ocean View Dishcloth from Goose Creek Knits alternates Garter Stitch and ribbing for a look that’s really interesting but still easy to knit. This one is worked on the bias so it adds a different skill but it’s still simple to knit.
The Lennox Washcloth from Cluck Cluck Boots has a fun ribbing pattern that’s great in a solid color, or try it in stripes for a different look.
Another fun thing to do with dishcloths is work a simple shape in a contrasting stitch pattern, such as this butterfly washcloth from EZCareKnits.
Increase the skill level by working a circle with the Fruit Dishcloth from StudioKnit. It’s worked in wedges and would be so cute to knit in a bunch of different colors (or to match the decor in your kitchen, bathroom, etc.).
Or try the Stars and Stripes Dishcloth from Faisdodos. This one is worked in the round from the outside in, using self-striping yarn to get the multicolored effect. So fun!
