Heavy Weight Cardstock

Did my own save the dates on an 80lb. cardstock.. Went for a more informal look. But now as I start to thinking about invites I'd love for them to be on a much heavier weight cardstock - in dark red! I've been searching forever and can't seem to find anywhere - I'd love to find some thats atleast ATLEAST 100lb in order to make some quality invites...
I've used Thepapermillstore.com for the STD - but does anyone know of any other good paper websites that offer some heavyweight cardstock in a variety of colors???

I came across this but it's metallic...

Actually, there are a bunch of dark red colors in heavier weights on this site...

Great site - THanks so much!! I am going to order a sample once its business hours so I can call them! I am so excited you foudn this! Thanks again!

I got my cardstock from The Paper Mill Store - their selection is amazing. http://www.thepapermillstore.com/pages.php?pageid=81

I got my cardstock over at Kelly Paper. They have lots of colors.

I think I'm getting all my stuff through www.paper-source.com

Or I may get the envelopments somewhere else, but do the rest of the invitation myself. Sometimes the invitations really stress me out- but the bride's the only one who cares, so I need to keep telling myself that!

This is my next project- thats my reason for the rant :)

I also got cardstock at Kelly Paper. It's by Stardream. They offer two different reds, Jupiter and Ruby.
