A few days ago, I was approached by colorlessblue. She had a pretty sock pattern made up of triangles, but it required her to use exactly 64 stitches around.
Her difficulty was that she couldn't find a gauge in which that worked. Me first reaction was to say, "well, that's not a big deal, the pattern is trivial to make fit on a multiple of 12 or 14 stitches." Then I tried to explain what stitches to remove, and it really quickly became messy.
So I stopped for 15 minutes or so and drew a few patterns. As I started, she clarified that she didn't want to purl.
However, the absence of purl stitches meant that the resulting pattern would be triangles of vertical knit stitches with a zigzag border of slanted stitches. So, my next thought was, "Why not make the slanted stitches into the motif. That resulted in this pattern: It's not perfect by any means. The k2tog and SSK being next to each other results in a ladder. Were I continuing that tangent, I'd turn all paired decreases into double decreases. Also, as it turns out, I didn't like how the paired yarn overs at the apex of the triangle looked. At the same time as I was thinking that, I also wondered what would happen if the triangles were offset by half a repeat, giving the whole pattern a longer period before it repeats.
This pattern (which is almost the same as a Barbara Walker one) has the property that the knit stitches actually form themselves into vein-like curves: the diamonds end up looking like oval leaves.
I tried knitting it half in knit and half in purl, to see if that would give the leaves more shape, but that ended up being a step too far: The lace lost enough of its definition that the pattern looked awkward and no longer anything like leaves.
I think I'm likely to use this one at some point, possibly as a motif one some leaf-patterned socks that I keep not getting around to. Before I do, I'm likely to put it through one more mutation, reducing it to about half the size and extending the widest part of the leaf by two rows, so that it more accurately matches the shape of a beech leaf.
Most of my charts seem to follow a similar pattern of starting point and progressive mutation, followed by a test knit, correction of discovered problems, a further test knit and possibly correcting steps that went too far.
It's like saying "just one more row", but "just one more change" instead.
