So I did throw away my green and white Sorbetto top. But I can't get this project out of my mind, because
1. The pattern was free, and fit pretty well, and I could really use some summer blouses.
2. I have another one cut out.
3. I keep seeing other people's Sorbettos online. The Sew Weekly did a series called "7 Days of Sorbetto", which showcased some interested variations (like piping). I also stumbled on A Good Wardrobe's more subtle and versatile takes on the pattern, like this nice neutral pintucked one and her black sorbetto with an inverted pleat.
So tonight, or maybe tomorrow, I'm going to wade in and finish one. My friend Leanne suggested the technique used in this bias tape finishing tutorial from angry chicken. It makes me think I've been attaching bias tape the hard way, if not the wrong way.
