hello @jansindl3r,
you can use the contours of the letters as a clipping mask, so the outside half of the stroke is not visible:
size(2000, 1000)
stroke(1, 0, 0)
strokeWidth(30)
B = BezierPath()
B.text('a', (110, 130), fontSize=1400)
# clip external stroke
with savedState():
clipPath(B)
drawPath(B)
# normal stroke
translate(1000, 0)
drawPath(B)
cheers!
