I got an email from the Assistant Editor of Interweave Knits answering my questions about the Fair Isle Bag. I am really impressed with the fast response. She said that the pattern is right and the color change lines are supposed to be there. If I wanted to get rid of the lines I could change it to a knitted garter stitch instead of a purl garter stitch. I have decided to go ahead and stick to the pattern. I actually think that it is looking pretty good so far. I took a close up shot of it so that you can see the lines better. Also, after further inspection of the pattern I realized that the top edges of the bag are going to get folded to the inside to form a casing for the strap. You won't really see this part anyways. Go figure.
