Apr PTEX from Diane, Inta and Troy

Diane does some beautiful pointed pen work and she also makes those cool flowers where you load a paint brush and make carefully placed an choreographed strokes.

Below is Inta's pretty handmade envelope. I can't tell if it is a cake or a hatbox or a painting intended to be ambiguous.

And below that is Troy's envelope. I like the organic feel of the lettering. But, I am confused about why he put two stamps on the envelope.

Oh, never mind. I figured it out. His envelope is really close to 6-1/8" tall. It is slightly under - so it would have been fine with one stamp.
But he was probably concerned - and decided to play it safe. Am I right, Troy?
