Crocheted Brimmed Hat, Japanese design

Here's the hat I made two weeks ago, modelled by my son. (I made two, but couldnt show it here until my sister got hers.) For the black one, I had some local acrylic yarns in my stash, I used 5mm hook, and it turned out quite big, but just right for my son. He didnt say he'd like to wear it though :p
Since I was looking for something to make for my sister's birthday, and I had some Carmencita yarns in a nice brown color, I made another one. This one was done with 4.5mm hook and it turned out to be just the right size. I mailed it to her in London on Mar. 27, and surprisingly it got there April 3, just a few days before her birthday :)


She spent her birthday and Easter vacation in Prague.
These are just some of the pics she sent me, and I played with it on Adobe Photoshop:


Btw, I'm not advertising the Carmencita yarns anymore, since they've already discontinued it. They said they got another supplier for yarns, and now they have Red Heart Yarns, which unfortunately is not the same as the Carmencita yarns that I like :(
As for the pattern for this hat, I got it from a Japanese book which I have a few more copies on sale. Details here ;) And here's a close-up of the hat.
