My first attempt at knitting mittens has me perplexed!. I knitted the mittens as instructed, placed 11 stitchs on "hold" and continued to finish the body of the mitten. Now, it's time to finish the thumb. I placed the 11 stitches on dpn's but there is no hanging/loose yarn to knit the stitches with! What did I do wrong and how can I finish the thumb?
