Trimming out an enclosed stairwell (to be carpeted) with 1x12x18ft mdf slipped between the stringers and drywall.
At both the bottom and top of the staircase I would like to end the diagonal trim with a vertical block, say 1x6x12", very slight chamfer on visible edges.
Problem, cannot find small chunk of mdf that is a full 1" thick. I've seen builders use a thicker horizontal board above doorways for accent.
This is Portland, OR and the best I can do is 5/4 lumber 8" wide, 16ft long and that would be a special order. Expensive!
Suggestions? Work-arounds? Thanks!

Glue up two thinner pieces.

It's MDF--it's already glue and sawdust with nice flat surfaces. What's
the objection to just gluing two thinner pieces together to get the
thickness you want?

If it _has_ to be one piece and you can't find it anywhere else, Boulter
Plywood <http://boulterplywood.com/> will sell you a quarter-sheet of 1"
MDF for 33 bucks and shipping. They can go as thick as 1-1/2" but you
noromally have to buy a full sheet for anything thicker than 1".

For something that's going to expose a vertical edge near the floor at the
top or bottom of a staircase though I'd go with something more tolerant of
abuse.
