I used some leftover yarn from my scarf...in this case Patons Colorwul yarn with a size J crochet hook.
Make a slip knot on the yarn and place on hook. (See my slip knot snap guide if needed)
Start chaining. I'm starting with a smaller blanket, chain 105.
Starting row 1: place a safety pin or row marker in the first chain from hook.
Single crochet in third chain from hook. Pattern: * chain 1, skip next chain, single crochet in next chain * repeat this pattern to the end of the row.
At the end of the first row, chain 1 and turn. Start row 2: *single crochet in the next chain 1 space, chain 1* repeat this pattern the whole row.
At the end row 2, single crochet into the stitch with the marker (might be easier to remove pin before stitching) then chain 1 and turn.
For the rest of the rows you'll follow the same pattern as in row 2, but at the end of each row, make a single crochet into the turning chain of the previous row. Repeat till your desired length.
Your pattern will start looking like this.
So I ended making a pillow out of the other yarn. And here's one that I finished with! I used 3 color: beige, light pink and maroonish. With a charcoal edging.
