Hey Salmonmac, thanks for answering. The version I have has stripes all the way down the foot, and that is where I am having the problem. I made it past the heel and as soon as I got done with the gusset I started having the problem. Thanks for the link to the ravelry pattern, I will link it up to my ravelry notebook.
So what do you think I am doing wrong? I have been bringing the color I'm working on under the other other strands, that is what the pattern says to do to avoid holes.
