Thanks so much for sharing your template!! I just created ours, except I ordered the plastic tags and loops from clearenvelopes.com. One pack of 10 tags for $3.60 and a pack of 10 loops for $2.80, which is great for smaller guest lists.
The shipping was fast...and they even threw in a few extra tags and loops (I think it was a mistake, but we had a few extra people RSVP that we didn't expect, so its perfect!!). These tags are a bit bigger than what the template fits, so we printed the front page and back page on separate pages (using 80 lb paper) and then cut out a larger piece of darker blue paper (leftover from our passport invites) to put between the two pieces to create a border. This makes it a little thicker (since I didn't use cardstock) and fills up the whole space.
Thank you again, Rebecca, for helping me create this with your wonderful template and instructions!
