I would have given it three or even four as it's very cute, but the instructions are a bit too BRIEF..... I can't see how it's marketed as simple, when I was baffled - and I am in no means a beginning sewer. I've been sewing for 30 years, made my own wedding dress, coats, jackets etc.-.... I love these project books though - when they're good! I bought this book mainly for the inspiration and partly for the hat pattern - I love hats. The brim doesn't fit the crown, and the crown doesn't fit the top. It is impossible to fit them together. Whether the crown is turned with the slightly wider circumference towards the brim or the other way. Furthermore, the whole thing is enormous. Something is very wrong with this pattern, and it ruins the whole book for me. I wouldn't recommend it to anyone.
Edited to add - there are huge amounts of people out there who have had problems with this hat, as I found out after doing a search on the net. And I am REALLY unimpressed with the author - I wrote to her website early August and a very sweet assistant told me she couldn't help but perhaps I would find a flickr group that could - they couldn't - and that Lotta would issue corrections or contact me after she came back from her holidays - she hasn't!
