Blue Celtic string

I like Celtic knots very much and have used them in my quilting, like the Celtic knot on my double wedding ring quilt. But I could never draw one. I found a link at Tangle Harmony to a new challenge at Creative Doodling. Judy posted a link to a YouTube video with very easy instructions to draw a freestyle Celtic knot and challenged us to have a go at our own design. I drew my string with a light blue colored pencil and after drawing the Celtic knot I colored it completely blue. At one edge I shaded it with dark blue. The twelve parts are filled with 13 different tangle patterns. It was fun and easy!
