Jen from iCandy Handmade created this awesome Curling Circles knit skirt for spring, and shares a tutorial showing how she did it. The skirt gets its name from the hem detail, which is actually a bunch of circles stitched down in the center with edges left to curl. If you have access to a die cut machine (like a Sizzix) and a circle die, you could save yourself a lot of cutting time, but you could also just cut them out by hand if needed. Get the tutorial.
