No it shouldn't make much a diff, there are seam cutter tools out there they may have then in Walmart or something like that around you it has a "U" shaped blade >======
would look something like that the blade facing to the left
with a handle behind it. or go with a nice sharp thin blade,
Razor or nice sharp knife. and it should come off sweet and easy, I would think after a wash or 2 the thread holes would be hardly noticable.
