I followed a chart for a Monstera leaf that uses crocheted chains, slip stitches, and double crochet. The leaf looks complicated, but it is a simple concept: make a chain, slip stitch into the center, make another chain, slip stitch into the previous rib, then turn and double crochet back to the start.

I don’t really like that there isn’t much to the center of the leaf. I’ll have to come up with my own pattern.
