So, anyway, I was thinking about the challenge and got the idea to use an outline of my hand for the challenge. The original intent was to color it with this technique but I had the forethought to scan it first.
I printed out a copy and colored it - and hated it. I thought, "maybe it's because I don't have much of a border around the edges (I used a Strathmore 5x7 Drawing Card)." So I decided to draw another string, use the same challenge tangle patterns and then color it. I'm still not fond of the results - and I forgot to scan the black and white version first.
I understand the concept. I just didn't achieve the effect I was hoping for. I will keep practicing. Until then - Happy tangling!
