I like that the top of my dress is still visible when I layer with a cardy rather than pull on a sweater. I find it easier to maintain an ideal temperature in a cardigan, too.
I cut down the center front of the sweater and then made a simple folded hem using the HeatNBond to give each side a smooth, finished edge. I then topstiched with this really cute rainbow variegated thread. ...Which turned out basically invisible in the cozy thickness of the material, but oh well.
I've already worn it way more in the past two weeks than I'd worn the sweater version during the previous year. And it seriously only took 15 minute to make. How cool is that?!
