First, I went to etsy for invitations. I found an amazing letterpress printer who worked with me (and that's a major accomplishment, considering how many revisions I made!) to design exactly the invitation suite I wanted, and then ran half of the set through the letterpress twice, just to make sure it looked perfect! He was absolutely amazing, and less than half the price of even some of the DIY kits I looked at!
Then I turned to etsy for wedding bands. I am super excited about this one (as I have mentioned before). I love our bands. I love that they were custom-made for us (even though they don't have an inscription). I love that they are titanium, so they feel a little special to me. I love the price (and I'll love the price even more if we ever need to replace one). And I love that the seller has an easy exchange policy in case we change sizes (since titanium can't be re-sized). I sooo couldn't be happier about this purchase!
I also bought Mr. L's wedding present on etsy, but that's a surprise! The seller was, as usual, great to work with, and I got a great deal on something totally personal.
The fabric that I was desperately looking for to cover the cupcake tower? Someone on etsy had some that was perfect (read: exactly what I envisioned), and for a steal! They were uber-responsive, and I had exactly as much as I needed, pronto! I think one of the best things about etsy is that the quality of the items I order consistently surprises me by being even better than I expected. This was a great example of just that. This was wonderful, heavy fabric!
Most recently, I had someone one etsy create the design that I printed on my cookie bags! I put up an alchemy request, and ended up with a design I love for a great price with great customer service. I also discovered the work of a great graphic designer, and I'm convinced that I'll come up with some excuse to buy something from her again in the near future.
