We often call the partial 'moons' in this tangle ladybug shapes. So why not actual ladybug drawings? You could even use red ink. :D
One of my favorite things to do is to add a small highlight to the 'moon'. Here's a tile with highlights, and also the original Crescent Moon with the 'moons' all black.
|Tangles: Beadlines, Crescent Moon, Pearlz, Tipple
The 'moons' don't have to be arcs. Try different shapes. Here's one with hearts.
|Tangles: Crescent Moon, Ixorus, Lotus Pods,
Paradox, Perfs, Tipple
Crescent Moon can be layered, instead of a single row, and it doesn't have to go all the way around the section. Try partial Crescent Moon and use it not on every side. Here's a tile showing both those ideas. (You can probably guess that the string here is a blind contour drawing of a bowl and spoon!)
The 'moons' don't have to be uniform in size. Try starting tiny and gradually get larger, and maybe back to small again.
Quite a different look is obtained if you leave the 'moons' white. I loved Julie Willand's crazy Crescent Moon from the Project Pack #10 video, Day 5. Here's Julie's example from the video, and mine from my booklet. She left the 'moons' white, so I did the same.
Go large! Draw very large 'moons' and fill them with something other than black. In the tile at the top of this post I've filled two 'moons' with floral-like things. Here's one with three leaf/petal shapes, each with a different fill in the 'moons'.
|Tangles: Black Pearlz, Hollibaugh, Hollis, Mooka
Sometimes I like to continue the 'moons' into the adjacent section, creating orbs, but leave the new half white. I find Tipple an ideal tangle for that second section. See the top of this post, as well as the third image, for examples.
Here's a tile with a several things going on. There are white 'moons', 'moons' filled with spirals and with Tipple, a partial Crescent Moon, a three-scallops shaped 'moon', and more.
Of course, you can also vary the lines and the centers.
But that will have to wait until another post.
