Well, I was showing my ex's mom my potholder knitting and she of course wanted one too. I had drawn up this turtle design for her a weeks before, but just never made it.
I was hoping to make it in black and blended brown/coral yarn, since I thought that would look rich and torte-shell colored , but she vetoed the black. She wanted the brown/coral with the green, but on paper the turtle design got lost and I even tried a swatch - yuck. Here's some of the other color combos that I tried on paper:

I ended up using Lily Sugar'n Cream in 'Sage Green' and 'Sonoma Print' which is a ecru color with short dashes of coral, brown and green. Note: the dashes of color bleed onto my towel as I blocked it. (frown).
I added the dots to the background to help hold the front to the back. And they ended up looking like sand or tiny tuffs of grass which adds to the nature look.
