Autumn from It’s Always Autumn shares a tutorial at I Heart Naptime showing how to make this faux layered ruffle hem and split back sweater. The design is inspired by a sweater she found at Anthropologie. She was able to recreate the look with a thrifted sweater and some lightweight yardage. Go to I Heart Naptime to find her tutorial.
