You got a winner there! looks much loved already.
Here's my newest one, not following the pattern originally started, more of a square (so far).....
Not sure what to do next, color-wise. I don't plan ahead, just like to fly by the seat of my pants, so to speak.
I think I'll need to buy more colors, for a light/dark effect. Maybe a solid darker brown, and a darker green. For the light, I'll need white and maybe a paler yellow? Off to shop!
