I decided to take the plunge and try working in different colors...The pattern is Invading your Earspace.
I modified it a little bit so there isn't a brim that folds up, and I'm only doing 3 images instead of the full two rows. For a beginner working with color, this was about as easy as I could have hoped.
My tension needs some work, but I'm just happy that the invaders turned out the way they should look! Now that I have the basic concept down, I'll work on the procedure a bit more.
