Try pressing some seams "with" and "without" setting them first.
See if there if a difference.
I've never actually done that - maybe I'll go down and try it! :roll: :oops:
I usually do - it only takes a few moments longer - I'm not into production sewing - but I think the seams press "better" to one side then and I have a "flatter" and "tidier" looking seam line
