Oh, this book may be nice to have or have for loan for couple of days.
I have book what may say about sister of this butterfly-book, so I have that flower book same style than this one.
Basic is that you look at those all beautiful patterns and do some of them - and then book lays somewhere (maybe you already loan that to your friend) and you just crochet or knt all kind of insects and flowers etc. Almost every pattern can do if just look model, exp butterfly: you need right colored yarn and then you quite easily create that butterfly you wanted to do.
Same basic pattern can tune so many different models - only your own brains can be different mind but do not worry about it - do what you want to do with yarn and needle or hook.
This is that commercial what I linked here, there is more interesting books also, take a look =)
