As a customer, you don't need to do anything in Templett to create an account. Your account will be created for you after purchasing from a Templett seller. We'll get the details from the order and create an account with the email provided in the order.
You'll then be sent an email with an access link to access your account and your purchased templates.
Please wait for that email to come through, from Templett. If you haven't received it, after 10 minutes, check your spam folder and check to be sure you're checking the correct email. Sometimes people purchase from an Etsy account with an old email address, or from a work email.
