often times, the o+s patterns ask that you press a seam open. if you're using a serger, what do you do? do you finish each fabric edge separately and then press it open? when i look at ready to wear clothes, though, about 9.9 times out of 10 i see that the fabric edges are serged together - so they aren't pressed open. in which case, if you do serge the fabrics together, do you just press it to one side?
at the moment, i'm sewing the seams with my regular machine and zig zagging each edge separately. i'm still not confident enough to sew and serge the seams in one fell go on the serger as it's hard to unpick those stitches.
