My Favorite bind off is a picot bind off using crochet hook. I used it in my Sunshine Top, Empire Top, and also in Lauri Dress. I like it because it makes a very flexible edging.
I am not sure whether there is tutorial about it, but the one I know is in Knitty Fall 2006 using knitting needle. When I tried, I don't really like the result. It flares too much. Thus I used my own method using crochet hook. Use the smallest hook possible and the tighter the better.
Step 1: Slip 1 stitch purlwise from left needle to the right hook
Step 2: Take working yarn with hook and pull it through both stitches
Step 3: Result
Step 4: Make 2 chains
Step 5: Insert the hook to the same stitch (that you slip in step 2), take working yarn with hook and pull through both stitches
Step 6: You just made 1 picot. Repeat from Step 1.
