Like a flash of light, our Nine-Note Double Seed Stitch Blanket starts with a pale burst at the center and flows into rich shadow by the outer edge. In a dauntless display of subtle value shifts, yarn reminds us, once again, just how much we love it!

The yarn here is our Nine-Note Bundle, a gently gradating series of nine skeins of 80% extra fine merino and 20% baby alpaca. Incredibly soft and wonderfully squishy, it knits up one heck of a cuddly blanket.

Part of the fun is that you start this blanket at the center, then work it in the round, increasing at the corners until you bind off around the perimeter. You finish by whip stitching the cast-on edge closed and wowza, a window onto a sunlit world!

One Nine-Note Bundle makes a Crib size for lucky babies, while two or three bundles make Small or Large Throw sizes for lucky adults. Choose from four palettes. We used pretty Rosebud and punchy Hyacinth, but wild Mulberry and soothing Tidewater are equally tempting!

You will also need…

Gauge

18 stitches and 36 rounds = 4 inches in Double Seed Stitch in the round (see Notes)

Note: We designed these blankets to use as much of the skeins as possible, so achieving this gauge is critical. To avoid running out of yarn, check your gauge, be sparing with your tails, swatch using the darkest color (Color I), and reuse your swatch yarn, if necessary. If gauge is a new concept for you, our All About Gauge tutorial is a helpful primer!

Sizes

Crib (Small Throw, Large Throw)

Finished Dimensions: Approximately 30 (41½, 53) inches wide x 32¾ (44¼, 55¾) inches long

Samples: The Hyacinth sample is the Crib size, and the Rosebud sample is the Large Throw size.

With right side facing you, turn the piece so the opening is oriented horizontally and the cast-on tail is at the right. Align the cast-on edges so the increases meet at the sides. Thread the tail onto a tapestry needle and insert needle from bottom to top through the lower cast-on edge, then from bottom to top through the upper cast-on edge.

Repeat this whip stitch for the remaining cast-on stitches, then thread the tail to the back of the piece to weave in.

Weave in ends and gently wet block to finished dimensions.
