Well, I usually only do one tangle for this challenge but found I couldn't incorporate all four of these tangles into my first attempt. Here it is with three of the four -
I enjoyed doing it very much and LOVE 'Xplode'. Adele's 'Xav' reminds me 1970s wallpaper but I found I couldn't do justice to 'Xeni'. The blank circle should pay homage to an amazing tile that Michele Beauchamp did recently using just Fescu - I was entranced by it and this is my diminished version of that. I can't provide you a link because it was on Facebook but if you took part in the Square One - Purely Zentangle challenge recently, you may have seen it. Awesome!
Anyway, the tile didn't satisfy my need to try out 'X' again, so I sat down and gave it my all. And I'm really pleased with the final result. Very different from the first tile and a thoroughly enjoyable experience, so thank you Adele and thank you Lila!
