I'm hoping someone will be able to point me in the right direction on this. I'm making a "traditional Chinese" top for tai chi. I'm working off of one of my teacher's tops--which I'm not allowed to take apart, blast it. Anyhow, the whole body of the garment--front, back and sleeves down the the elbow--is one piece of fabric. There's a pair of curved gussets at each armpit. I can see how to do gussets where two seams meet, but am having difficulty in figuring out how to do them just along a single seam. I'm not entirely sure they're needed, as it's a pretty loose top to start with. I did manage to get one of the gussets sewn, but it's all puckered at the point, even after some judicious trimming. Is there some trick to it or do I just need to try and try again (that's why I'm working muslin!).
