The Zentangle Challenge (#88) for this week from www.iamthedivaczt.blogspot.ca is to use the official tangle "IX". I haven't used this one before, and I love the challenge and exercise to use a "new to me" tangle. The first one I did I wanted to play with adding in another tangle, and jetties seemed to just jump right in. I also wanted to play with the darker ends of the first lines and see what happened if I inverted or extended them... I'm happy with the result.
The second one I did using the Zentangle String #5 because I thought it would present another challenge since none of the lines actually crossed (though I did change that a bit...) I like this tangle and will probably use it again, but I'm really curious to see how others have changed and adapted it. Thanks for taking the time to look, and I appreciate any comments.
