For winter warmth, two options: armwarmers in an interesting spiral stitch, or a set of fingerless gloves. The armwarmers as pictured are a full 17" long; the fingerless gloves come to mid-forearm. Either can be customized to be longer or shorter, and to fit bigger or smaller arms. Pattern price for both: $6.00
For the armwarmers, you'll need three 50-gram skeins Koigu Premium Merino (KPM), in different colors that you like (those pictured are # 2160 Purple, # 2130 Turquoise, and # 2120 Magenta); PLUS one 50-gram skein Koigu Painters Premium Merino (KPPM) P123, (E) a few yds of KPPM No. 805. To make these in one color, you would need about 350 yds (two 50-gram skeins) of Koigu. Use a size G-6 (4mm) hook. The gauge is 3sc (with spiral st chains and triples between) = 1.5 "
For the fingerless gloves: One 50g skein (175 yds) Koigu Premium Merino (KPM), # 2235 Burgundy; size H-8 (5 mm) hook. Gauge 19 sts = 4” in cable pattern.
Note on Yarn Substitution: Either of the patterns can also be done in any of the following yarns: Claudia Handpaints Merino sock yarn; Blue Moon Fiber Arts Socks that Rock; Fleece Artist Basic Merino Socks; Cherry Tree Hill Merino Sock Yarn; Louet Gems 100% Merino wool.
