I'm at the point where I have to overlock, and the machine is set up with white thread. If changing thread always went well, then I'd just do it. But it's a 50:50 thing with this beast, so I have until I get home late from a massage to decide. I pulled a muscle in my back on Saturday and I probably shouldn't be sewing cos it's already owwie. But LOBSTERS!
Thankfully my stash of overlocker thread was unpacked, though I'd overlock with dark navy not black. That way if there's any unpicking it's easy to spot the thread on the black fabric. It's purely an aesthetic decision to switch from white, not a functional one so it's only my inner perfectionist that cares really.
I also remembered to get back to my old habit which I've not mentioned here of stitching off a seam or dart onto a square of the same fabric. It reduces the thread wastage and helps the bottom thread tension remain stable (no need to old the threads as you start the seam) which some machines have more problem with than others.
I also do production style stitching, I have everything pinned that can be and just sew from one dart to the next dart or seam until they're done, then switch to overlocker and do the same. Then press everything, then pin the next batch of seams and repeat.
Oh, and just in case I have to unpick, the bobbin thread isn't black but a very dark charcoal, so that I don't risk my mental health trying to find black on black.
