I've always been fascinated with these Celtic Knot designs, and really enjoyed Sadelle's videos. This was my first attempt and it turned out a little different than my original sketch, but I may give in another try in the future.
Once I started working the design, I really wanted to emphasize shadows where the lines move under. This started with watercolor pencil and then added colored pencils for more shading. This was so much fun to work on and very meditative. Thank you so much, Sadelle!
