First time using puff pastry

And AFTER the egg wash, take a paring knife with a good sharp point, and very lightly carve a design (wavy lines, a vertical-horizontal grid, use your imagination!), just going through the first very top layers of the pastry. After it is baked, the results are beautiful!

I'd say put it on just before baking because you want it to stay chilled.An egg wash on a yolk mixed with cream is a nice touch. Yum.
