Believe it or not, this is a very easy drop stitch pattern! And it looks so fun! Here's a nubbly little detail:
See how those stitches between the nubbles have fewer rows than the rest? That's where you drop the stitch over 4 rows and pick it up with the same color as below. So no intarsia or knitting with more than 1 color at a time. Not that I mind doing that either, but this was much faster to knit that I had imagined, because you only do something out of the ordinary every 6th row.
Another one I tried was the fretwork pattern, based on the same idea of only knitting with one color at a time. This one uses slip stitches instead of dropped stitches. The colors are a dark cholate brown and a light greenish blue.
And a little detail shot:
This became my immediate favorite! I'll have to use it in something else, too... hmm... the possibilities...
