I got a late start on this, but had fun getting to know U!
I used Undling, Umble, Uncorked, and Uni. My new Strathmore Toned Gray sketch book was calling to me, so new tangles on new paper.
This was more challenging than I anticipated. The texture of the paper is different than official tiles, and the color requires some new thinking. But here is what I got, and after this sporting event on TV, I will give some thought to "M".
