Hello,Back in the day, we used to get this kind of stuff from: http://www.beveridgepaper.com/We used it for cd packaging, business cards and the like, as it’s thick like chipboard and comes in colors, though I’m not sure it would be great for anything that you might want to be archival. You could probably ask them about it and see what they say, but I remember it being a glorified construction paper/chipboard combination… great for fun projects, but maybe not something wedding-y?Oh, another thought would be to duplex a stock you like. We just had some success with this, just by using Studiotac and brayering it between two sheets. A bit time consuming, but I was really happy with the results, got to choose my paper, and thankfully didn’t need too much.Jen
