I am very much a beginner at knitting, but have someone I can go to for help. I am wanting to knit a reflective scarf (probably infinity scarf) for dd. When she goes to secondary uniform is dark, coat is dark and the route is in places dark in mid winter. I figure a reflective scarf won't be too uncool (well no more uncool than any other scarf) and might buy an extra few seconds of visibility. Any recommendations for yarn to use that will be soft and snuggly (she likes snuggly things) and reflective?
