Whatever variation of the pattern you use, it combines a series of increases and decreases that aren’t right next to each other, which makes the edge of the fabric scallop in a really pretty way.
About a year ago I did a roundup of some pretty patterns using Feather and Fan (including a washcloth and scarf that I “designed”). There’s also a simple scarf on Knitter’s Review that is a great introduction to the stitch.
This is a nice gateway to more complex lace stitches because it’s still a really easy repeat but it looks fancy and is just a lot of fun to knit.
Have you ever made a project with Feather and Fan or Old Shale stitch? I’d love to hear about it!
