The Seaside Knitters use all their talents to solve the mystery while they continue knitting tiny ornaments for the first annual tree-decorating contest. Although Izzy is the lead character, I always find Aunt Nell solves the mystery in a more theoretical way.
The relationship among the generations featured in this book is what makes them so special to read. For example a group of knitters meets once a week at Izzy's shop. The same group and their spouses or significant others enjoy a weekly Friday night dinner at Aunt Nell's home and they all contribute something delicious to eat. Sunday mornings finds them informally gathering at a local restaurant. I enjoy the conviviality of the group and the moveable feast they provide.
