I have wanted to make some crochet boot cuffs forever. I pinned a few on my crochet board on pinterest. The two best free patterns I have found were at Love2Bloom (best instructions) and Crafting on a Dime (I liked the looks of this one the best). I ended up using the crafting on a dime pattern the most, and tweaked it a bit for myself. I like that you can reverse it if you want the ruffles to show or not. I just found the pattern a bit confusing, but you can figure it out!
