A link to your files will be send to the email address you provided. Check your spam folder if you can't find it anywhere.
If you make an Etsy account you can always download your files again, even later on. Just go to "You" (top right of the screen), click on "purchases and reviews", find the right order and click "download files". Handy!

And of course, if you really can't get to your files for whatever reason, just send us a message and we'll get you sorted.
