This scarf pattern is light and airy, perfect for those last few chilly winter days that are hinting toward spring. Choosing a yarn containing alpaca provides warmth without weight. The stitch pattern is reversible, looking great on both sides. The Lacy Rib Stitch Pattern is easy to remember, using knits, purls and yarn overs. The sport or DK weight yarn uses a size 8 (5 mm) needle.
