you can basically just pick them out with tweezers but only if you've cut around it already. kind of hard to explain
not the cleanest job by any means but just been a bit busy lately, my unc pair is still how it is.
also had to deal with trial and error, if you look closely near the sockliner in the first pic, i have that piece of canvas there for it to stay intact, i accidently ripped through the seams.
in the second pic of the same area i just seam ripped through it in a cleaner way where the khaki is still visible almost like a line.
the hardest parts for me is stripping around the parallel stitching, like i said not the cleanest job but I'll get around to trying to clean as much of it as i can.
