Overshot Color Choices

I am still working on getting a Weaver Rose draft on the Baby Wolf loom. I have been thinking about my color choices. Using 24/3 cotton as warp, I am thinking I will be able to use 10/2 cotton as pattern weft. But of course I will need to see how it works. I think that is called "sampling". Yikes!!

These are the colors I hope to use.
