My girls love to wear sweaters, pretty much year round. And considering they wear the same sweaters over and over and over again – I don’t mind taking a little bit of time to make them extra special. The ruffled cardigan tutorial has all of the elements that I know my daughter will love, from ruffles to colored buttons.
