How to knit a wavy edging before binding off

Hi I am knitting the Eyelet Lace Shawl from Ravelry which calls for a picot edge bind off but I hate the picot bind off edges cuz they always curl on me. What I really want is to make a wavy edged bottom and then bind off but I dont know how to do it. I’ve only been knitting about a year. Can anyone tell me how or show me some directions for creating this affect? Thanks!

To make a wavy edge or ruffle you can increase every stitch or every other stitch across the row, then knit a few rows in stockinette and bind off. How many stitches you increase depends on how much of a wave you want. Liat Gat recommends blocking and shaping the ruffle edge with your fingers while wet.
