"temporary" desktop... six or seven years ago... that I've been
thinking of dressing up with a hardwood edge. One cheap trip to HD and
I could be using biscuits to attach it. Thanks.

For a number of years, I've used an invisable nailing kit for attaching trim
and face frames.

Alternatively, I've just hammered in a finishing nail, countersunk it and
then filled the hole with a wax filler stick fractionally darker than the
wood itself. It results in a hard to recognize attachment point and is about
as easy to use as it gets.

There's always alternative ways to attach things.
