This mitten pattern compliments the cowl and hat that are in my pattern store! The adult size is an average woman’s size and the child size fits roughly 3-7 years of age. If you are going for toddler size I would try a 4mm hook and for a larger adult mitten I would try a 5.5mm but I have not yet attempted these sizes. The pattern includes a fingerless version of the mittens, for both sizes as well. There is a short picture tutorial included in the pattern for the double crochet spike stitch that is used in the pattern. This pattern is written to US crochet standards.
