The book contains 10 patterns, nine for tea cosies and one for a cafetiere cover. All the cosies fit a standard sized teapot. The gauge is not vital as all yarns are aran/chunky equivalent. No more than 200 grams are needed for any pattern. DK yarn can be used but you will need to use it double. I have used selected colours but these can be changed. I have kits for all the patterns and stock the yarns.
