In the August 1966 issue of Popular Needlework, Elizabeth Hiddleson wrote a Let’s Crochet article and writes:

I am waiting for my printers to complete my #14 book, - then #15. I would like to have these ready for all my ardent crochet customers to order in the early fall so they can get started with the cool, then cold weather in some parts. Then, in the future, likely in 1967, I hope to work out my #16 book, which will include several of the bead doilies.
