This first stitch I really like and will likely reuse. It's consistent and a good mix of solid and lacy. It's also fast: it grows at the speed of dc, and is essentially mindless. The baby blanket I made from it is really nice, and it would be appropriate for scarves, afghans, shawls etc. Additionally, basically any color striping pattern you'd want to try out would work with this stitch. The pattern for this stitch is easy to read, and would be a good one to start on if you're not confident in your ability to decipher crochet-script. This stitch gets my ringing endorsement for both novices and experts alike.
Here's the pattern:
Chain 93, then work the stitch until fabric is square. Add the standard baby blanket border to finish.
Round 1: sc around, 3 sc in corner
Round 2: dc around, 5 dc in corner
Round 3: sc around, 3 sc in corner
Round 4: (sc, ch 3, sk 1) around, (sc, ch 3, sc in same stitch) at corner
I made this with Lion Brand Pound of Love yarn in Lavender with a J hook.
