Don't worry, they're intentional.
Here are some photos of a crocheted scarf I designed this week for Needleworks, the yarn shop I work at.
It takes just one ball of Noro Silk Garden Sock, and measures approximately 54"X6" after blocking.
You could use Noro Kureyon Sock to make a longer scarf, or a second ball of the Silk Garden Sock.
Yes, those photos are both the same scarf. The lower picture, shot without flash, shows the texture nicely. The upper picture, shot with flash, shows the holes being blocked open and is a more accurate representation of the colors in the yarn (though it's somewhat less orange than it appears).
The pattern should be available soon on the Needleworks website, in our Pattern Library.
