I am going to make another shirt with 3/4 sleeves and the turn-back cuff I designed. I have it cut out and have the interfacing applied. I like the So Sheer iron-on interfacing for shirts, since it is easy to apply, has a good drape, and lasts through many many washings.
Here is the same pattern, different fabric. It has princess seaming, and though the pattern originally came with a short sleeve, I lengthened it into a 3/4 length. This is one of my convention shirts for events like Stitches or bead shows. The bright prints help my companions spot me from across the large room.
