This book has instructions for 20 different flowers, plus a stem, plus 4 different leaves. (Pansy, tulip, anthurium, bluebell, carnation, rose, water lily, azalea, sunflower, violet, primrose, dahlia, lotus, cherry blossom, hyacinth, Christmas cactus, daffodil, iris, lily, narcissus.) There is very little `sinking', which is nice since I'm a low to mid intermediate origamist, only 4 months doing it, but I love it! The book is spiral bound thus lies nicely flat; the illustrations are beautiful; the instructions are right with the illustrations. His mountain fold is a solid line instead of the dot-dash I'm accustomed to, so you have to get used to that.
The paper that comes with the book is simply gorgeous; I haven't used it yet, want to be sure I can follow all the instructions so I don't waste any of that beautiful paper. Only one minus, and maybe it's just my perception: and that is, the folding illustrations use Langeveld's paper, and sometimes that makes it a bit difficult to see exactly what one should do. Maybe if I wasn't such a wimp, and just went ahead and used his paper right away, the instructions might be a whole lot more obvious. But, I just don't want to have to throw away any of those lovely sheets when I make a horrible boo-boo! I'll get there by and by! And, by the way, there is special paper for the stems and leaves as well as for the flowers. It would be absolutely delightful if he would market that paper by itself (not have to buy the book to get more of it); the paper is really special! Hey Joost, do you hear this?
I love making flowers and have completed many types from other books and off the internet. Pansy, tulip, bluebell, lotus, iris, lily, etc etc; Langeveld's instructions for those and others is different, not worse, not better, but different (well, maybe better sometimes), and it's neat to learn other ways of doing things. More than one way to skin a cat! Like, it's not the blow-up tulip, for example. And the iris and the lily have more than four petals. Cool!
Five stars for sure, and I'd give five stars to a separate purchase of the 100 sheets of `specially designed paper' if it was ever made available.
