Mattress stitch argyle

Hey everyone! I need to do some mattress stitch up the back of my argyle socks. The main color is dark blue, and the seam will also be running through the middle of a cream diamond and a light blue diamond. Do I need to change the yarn for the seam as I go over each color block, or can I use the cream color to seam all of it, since you really won’t be able to see it? Thanks :slight_smile:

I’d try it with one color and see how it looks. :shrug: You probably won’t be able to see it with mattress (love that stitch!), but you always have the option of changing colors if you want.

I just seamed mine up yesterday and I used my main color, gray. You can’t see the seaming thread at all.
