Nice and manly knit pattern for a guy's scarf! Cast on 35 stitches. Rows 1 and 2: Knit. Row 3: *K3, P2*. Repeat from * to * across row. Row 4: *K2, P3*. Repeat from * to * across row. Repeat Rows 3 and 4 until scarf measures approximately 65 inches in length. Knit 2 more rows. Bind off.
Add flannel lining to crocheted blankets. I've never liked how airy crocheted blankets are - they let the cold air through (what's the point) and little fingers can get stuck. This is an option, though I would choose a different stitch pattern.
