This model is in N-Scale.

I have cut out and glued in place a
Wall (rear), sidewalks and the
subject of this section - the curbs
at the driveway entrance.
I used a paper cutter to cut the curbs
from some Concrete scrap.  Using the
paper cutter guaranteed that the curbs
were straight and even.  Scissors work
good too.

I ran a bead of testor's model cement on
the bottom of the curbs and then wiped
it off so it wouldn't bleed.  Real Road is
flexible so I cut the curbs straight and
then bent them to fit.  I used a ruler to
make sure they were straight as I glued
them in place.
Remember that this model is in N-Scale.

Have you ever seen curbs like these before?
Me neither.
