I purchased a BRIDES invitation package from Michael's with coupons making it .75 per invite (pocketfold, response card, addtional card, invitation, envelope). Then I created the design and printed them myself. I also purchased different ribbon than what came in the box. With the cost of the invitation suite, ribbon, and ink it ended up being $1.25 per invite!
There are bigger pictures in my bio as well. Also, we got a different wedding band for FI, the groom and GM outfits, my shower dress, and the flowers done! We also did a few other DIY projects but I need to take pictures of them =]
