i've got white gloss kitchen units and originally didnt buy a
cornice / pelmet but soon after realised it looked like something was
missing. so i bought the white gloss cornice/pelmet (same top and
bottom) from b and q (kitchen from homebase). first of all i'm hoping
it will be an exact match when fitted it looks ok but you can never
tell.

anyway i have a cutting machine which can be tilted to 45 degrees. my
plan is to measure the cabinet widths and depths and cut the wood to
the right lengths with the mitre joints. then glue the joints with
clear silicon before fitting to the underside and top of the units
with screws. i guess cutting from the front (gloss side) is best for
smooth cut.

any tips before i attempt this tomorrow/sat is appreciated.
