Did you know that when you buy a pattern on icelandicknitter.com, your PDFs will be stored in your Icelandic Knitter account where you will always be able to access them? If the patterns were to be updated, they will also be updated in your account. To access the PDFs, simply log in and go under Downloads. If you have forgotten your username/password, enter your email address and click on Recover password.
Hope that helps!
