I got access to an overlocker yesterday and used it to serge the seam allowances on some trews I'm making - what a difference to using the single needle 'overlock' stitch on my sewing machine (and indeed to doing it by hand). Anyway it got me thinking - what's the correct point to do this?! As I see it options are:
-Immediately after cutting out (at that point hopefully no need to use the cutter on the serger so seam allowances stay true to the pattern).
-After initial ironwork but before making up (the overlocking would prevent stretching otherwise). Risk that seam allowances get trimmed.
-One the garment has been basted up or sewn?
Any thoughts or guidance would be much appreciated. I will post a thread on the trews once they're done..!
