The only way to access previous orders is through your email order confirmations. If you don't happen to have them, you can log into your account and find the order number you want and email sierrampoulson@gmail.com to have the confirmation resent where the download links will be.
If you purchased via our Etsy shop, you'll need to log in to your Etsy account to find your downloads under "Purchases" or via your email confirmation sent to you by Etsy.
