|I have no idea if this is widely done so I thought I'd toss this out as a tip. When I trim various seams and inner construciton, I frequently use my Pinking Shears rather than Straight Shears to remove excess fabric. I recently made a tailored jacket using a light weight wool (similar to wool crepe) and this method helped a lot. All the edges of welt pockets, bound buttonholes, collar seams were done using the Pinking Shears. This method softens the edges and eliminates a straight line impression should you over-press or if your fabric is somewhat sheer. I also "pink' the edges of interfacing pieces fused undeneath pockets and buttonholes, just to be sure it doesn't show through as a rectangle to the right side.
Another benefit is the elimination of clipping little wedges or clip-lines, to ease pieces into a tight area such as a neckline. The zig-zag edge allows you to spread the piece without making all those little clips, which I think sometimes show through to the right side.
Pinking Shears are made to cut one layer only (or they will go out of alignment) so be sure to follow that rule. Try this method - I think you will like it!
