Well, that's when I usually find them anyway.
I was doing the last bit of tidying up on a top, stitching threads in, trimming bits etc etc, when I thought...
Hmm, that sleeve doesn't look right. Of course not, it's inside out!
So now I've to unpick that side & take the sleeve out & re-do it. And I thought I'd finished for the day. Luckily it's a knit & the front & back are the same pieces so no changes to be made otherwise. just as well as there's nothing but wee scraps left.
Ah well, have a cuppa then back at it.
