One of the things that I have done on all my homebuild projects over the years, is to add a topping out piece. For The Den, I recycled a carving that I picked up on tour somewhere abroad. For years it has made a nuisance of itself on window ledges and cupboard tops, providing a home for spiders, and terrifying Orcses with its smile.
Its final resting place is a corner cunningly prepared for it in advance* There only remains to finish of the soffit boards outside and a few other bits of touching up until the electrician calls.
Why Eddie Lizzard? Just look at the eye makeup!
*Though not as cunningly as the floor.
