Help! I’m teaching myself to crochet, and after some practice learning the various stitches, thought I’d try a cute spiral scarf with “simple” instructions. The pattern specified using two yarns, one skein of each. For the first part of the scarf, the directions say to use two strands of “skein A”, held together. Since I bought only one skein A (and one skein B, as directed), how do I get two strands of yarn A? Do I divide the skein and then hold one strand of yarn from each half-skein? I’d love to have some advice on this.
