How to Knit Hedgehog Mittens – DIY -> make a hedgehog and an otter one for each hand and you've got John and Sherlock! now to find an otter mitten pattern… <-the hedgehog would have to be for the right hand, because John is Sherlock's right hand man :)
This motif comes from an Estonian mitten pattern. You can see the mittens here. Muhv has graciously permitted me to copy her combination of traditional stitch patterns for the cuff she added to her mittens.
