Socks, I could not access the link, but I think it's my problem, not yours. For me the most successful way to weave in ends without bulk is the way I do it for my socks. If I am using 4 ply yarn I separate the ends and weave in each ply separately. It is tedious work, but almost impossible to detect.

You won't need to weave in any ends as that is a crochet pattern......the chance of colors comes with the rows.

When I got to work and used a different computer I had no problem accessing your link. Linda, I don't quite understand why you think there won't be any weaving in of the ends. When you get to the end of the first row you change colors. When you get to the end of the second row you change back to the first color, but the end of the yarn is at the other end. You need to start with another piece of yarn, unless I am reading this pattern wrong.
