Designing Lace Patterns

Dear users, dear authors,
How do you design a pattern with a phenomenal lace pattern?
Let me know.

Well, whether my lace patterns are phenomenal is for others to decide. For me, the yarn is always there first, and then I decide what it’s suitable for. Then a vague idea comes to mind, and I start knitting. Knitting can also be replaced with crocheting.
So I knit a few rows and take a look at the whole thing. If I’m satisfied—which happens every now and then—I keep knitting; if not, I start over or scrap the idea.
What I think is important with lace patterns is being able to “read” your own work—that is, recognizing what you did in the previous rows and what might fit in there now. It’s also important to understand how individual stitches behave and what kind of pattern they create. And then, of course, those stitches have to come together to form a cohesive whole.
But that’s not just important for lace patterns—it applies whenever you want to design something yourself. You simply have to know what happens when you do this or that. It’s probably the same for every design process.
