Done with 2B mechanical pencil on an A4 piece of cheap recycled acid free printer paper. I didn't adjust anything after scanning, just put my username there.
I only used my eraser to erase part of Dean's jacket and to try and fix his smile.
My shipper heart hopes that Dean and Castiel go get married in a little chapel in the middle of a country town, with a giant oak tree out front and lots of flowers in the long green grass.
Ahem.
Enjoy

"Time for a Wedding" is an upcoming episode and from the preview it's actually Sam getting married.
So you didn't miss anything ^_^
I used to be a Dean/Cas shipper, but...S6 Cas pissed me off and made my ship do a Titanic.
Btw, maybe Dean IS meant for Cas. After all, did you notice the lack of female interaction Dean has been suffering lately (especially when he had to pep talk himself into it in 7.04 and seemed REALLY uncomfortable with the psychic girl last night)? He even admitted to trust problems to Sam stemming from the loss of Cas.
