Jersey is usually floppy rather than slippy, but not all that difficult to sew. The main things to watch out for are:
- before cutting, check in case the knit is twisted. This is not unusual in cheaper knits and there isn't much you can do about it other than be aware.
- when cutting and when sewing, be careful not to stretch areas that would be the equivalent of on the bias in a woven - the effects are much worse. If you've cut a curve, handle really gently and stabilise as soon as you can.
- skipped stitches. You can sew jersey on a normal sewing machine just fine, but make sure you have the right needle in as this can exacerbate the skipped stitches problem.
- curly edges. A lot of single jerseys curl at the edges - spray starch can help this, but it can also be a nice decorative effect.
