Cabin Fever vs. Celtic Knots

Cabin fever, Day 11.  Another couple of inches of snow, on top of the ice, on top of the snow, on top of the ice.

Can't go out, too old to sled, too lazy to clean house. What to do? Zentangle, of course. But today I'm playing with Celtic Knots. I've always wanted to learn to draw them (and there is an actual Celtic Knot Tangle) and found a wonderful Youtube channel called The Celtic Goldsmith. The first lesson in his series is drawing the Celtic Triskele, perhaps the simplest and oldest documented Knot. Here's the "stepout" (a series of steps to draw a tangle): 

Not terribly difficult, if you follow instructions, and don't go merrily drawing the next step without checking the previous one, like I did in the crossed out step in the second row. Now for some tiles:

First the obvious. Four Celtic Triskele, with Betweed, Paushkalov (aura'd), on a background of Tipple. Except for the Celtic Triskele, all of these patterns can be found at tanglepatterns.com.

Next, I tried using the Celtic Triskele as a string, filling with Cadent, Fife, and Ditto. Again, these tangles can be found at Tanglepatterns.
