Scrap Pet Blanket

I have been working on this pet blanket, using scrap yarn for a couple of weeks. I tried to make one of these earlier this year, but made the mistake of using different sizes of yarn, not so good!

I am working on a collaborative project that I am excited about, but it is a big project and so I have been alternating with this little scrap blanket. I need to find an additional color to add, but want to stick to the true theme of the blanket, and only use leftovers. I may have to root through someone else's stash...
