matte jersey skirt, cut on bias or not?
I just figured out how to make an elastic waist skirt with flat elastic instead of it looking all gathered. Great, but when I serged the side seams, it streatched about 4 inches and it doesn’t hang very well. This fabric is a matte jersey with spandex and it stretches both ways so I didn’t think to cut it out on the bias. Should I? And what can I do so that it will not stretch when serged? I am trying to duplicate a skirt I bought so I don’t have a pattern to go by, I had to make my own pattern using the ready-made skirt as a guide. Do I still cut it out on the bias and how do I serge it without the incredible stretching? Thanks
