I have not been successful with lace. What made it "easy" for you? Your work is beautiful!
It could help to try with a thicker yarn first, if laceweight is being difficult. I find that sometimes with patterns really full of YOs (my favourites), the YO gets over the next stitch and if you don't pay attention it's easy to knit both together on the next row. That kind of thing is easier to see on thicker yarn. I started knitting lace with fingering yarn, and I'm just now using my first laceweight. Or maybe, you could swatch the pattern repeats in thicker yarn to see how it goes and then tackle the real project in laceweight. Done that too, once, with a pattern that had a mistake on the chart. I kept trying and it didn't look right, so I got some other scrap yarn and swatched, experimented changing the chart, until it looked right.
