12x12 hardbacked envelopes - where from?
When I have swapped papers or CS I have always had to use a pizza box, and a few sheets seem stupid in one of those. Plus, I don't often have many, as I tend to do very infrequent larger shops, rather than lots of little ones, so sometimes I have to stay out of a swap I'd like, because I haven't had anything to post the stuff in.
A couple of swaps have turned up in 12x12 hardbacked envelopes (which are reused pretty much immediately LOL). Can you get these easily, as I have never seen them in our PO or WHS or anywhere?
