I did block it before sewing, but must say I can't really see any difference... here it is, before and after blocking:
I found the buttons when I went yarn shopping Tuesday, and just knew I had to have them! Aren't they adorable! Here's a close-up - taken at an angle as somehow that also made the colour come out better. It has looked almost grey in the other photos, but it really is more green'ish.
I've updated the pattern with gauge, size and amount of yarn used. Would you mind taking a look and seeing if it makes sense now?
Now to wait for niebling#6 to make his or her appearance :)
