Re-Post: Envelope Question

I am DIY my invites. Well the kit came with envelopes and I really dont like them too much. Ive been searching online for envelopes that will be easy to print on from my inkjet printer. Does anyone know of a site I can buy envelopes from? Also, I came across some that were made of 'linen' Never heard of such a thing! Im wondering if they will be easier to print on.

Thanks for the help girls!
