I found it helpful to imagine a line across the paper as I was drawing. That helped ensure that the tops or bottoms of the points and arches line up (more or less) and don't get too out of whack as the pattern develops. The stripes can be filled in different ways for variations. Here are two tiles with Parch.
|Tangles: Dust Bunny, Finery, Paradox, Parch, Prestwood|
|Tangles: Florz, Gewgle, Hibred, Parch (x2), Spinners... |
and something Jane Monk does that I really like!
