I really love the wrong side of treble stitch.
The "wavy" effect looks pretty in solids, and it's very nice this space-dyed yarn, too.
I wondered why the yarn in this beret self-patterned into such clean divisions in a patchwork effect.
Here's what I found: On the right (smooth) side, the changing colors interlock on the diagonal.
On the wrong side, the old color aligns itself vertically with the old color block, and the new color, with the new color block.
A small discovery . . . and another reason to love the wrong side of treble stitch.
