I am a bit behind as I have just recently discovered this, but each Monday a new Zentangle challenge is posted here. You can also find it with the button to the right. I know I need to work out of my regular "box," so I tried this week's challenge. It was to use only straight lines. I like designs made up of straight lines, so I thought it would be a piece of cake. Wrong. I started 4 different tiles and only finished two of them. I discovered that while I like tangles with straight lines, I do not like starting with strings that are straight. (For more information on what I mean by tangles and strings, go here.) Here are my finished tiles. I will post the unfinished ones as well, as soon as I work on them a bit more.
