I'm back to working on non-State Fair projects. While working on another scarf that didn't quite turn out the way I wanted, I learned this design technique. Putting aside the disappointing project for a later time, I knitted this scarf to incorporate this interesting ribbing design.
The mid-weight (sport? DK?) grey and silver yarn is Studio Samples by Nicole purchased at A. C. Moore and the fiber listed on the label is "mixed fibers"... probably the grey is acrylic with polyester silver thread adding sparkle. I used five 50-gram balls of the yarn for my scarf.
The scarf is knit in garter stitch with some of the stitches dropped on the last row, and then picked back up with a crochet hook in a fashion similar to making a crocheted chain. After all the dropped stitches are chained and back on the needles, the last row is bound off as usual.
I cast on 37 stitches using the long tail cast on method.
For the first stitch of each row: move yarn to front, slip 1 stitch as if to purl, move yarn to back, and knit to the end of the row. This gives the sides of the scarf a smooth, neat edge. Continue this pattern to the desired length.
For the last row (knit 5 stitches, drop 3 stitches from the needle) 5 times, and then knit the last 5 stitches. Pull the dropped stitches all the way to the beginning of the piece so that you have wide strands of yarn separated by the columns of garter stitch. The dropped stitches will be chained up to meet the stitches remaining on the needle. The dropped stitches are worked in groups of 4 with just the first 4 given a half twist before being chained to the next 4 strands.
The result is a thick line of V-shaped stitches lying against a garter stitch background that makes for a more interesting scarf than simple garter stitch.
