I need hand cards so I can try out the techniques given in this wonderfully odd book - I only say "odd" because when anyone discovers that I've been saving wolf hybrid/malamute hair for a dozen years, I get "odd" looks from folks!
It's well thought out, has sections that discuss the differences in types of hair/fur & the appropriate fiber(s) to use along with them to produce the best yarns. They walk you through collecting the hair (methods & what hairs to collect), how to prep the stuff so it's ready to be made into yarn, how to card it, spin it (along with tutorials on types of spinners!), dye it, measure it, and includes a few patterns to try out your homemade yarn on (e.g. Golden Retriever Scarf, Pill Box Hat of Cat Hair - there is no partner book for cat hair, I checked), though they may not be to my taste, they are great get-acquainted projects.
So, for this off-beat, small audience title, I have to say thumbs up - if you're reading it, it's because you're interested in the subject matter and WILL find lots of helpful information & tips. If you have never owned a dog, well I'm sorry for you... as well as knowing you wouldn't find this book the Cat's Meow ;)
