Look for pattern by number at the stickatillbarbie website. Files are doc files or PDFs. When you get on to the website, you’ll find the patterns listed on the left, by number, grouped on pages … 1,000 of them, not including accessories like hats and scarves, which are listed in the accessory section closer to the bottom of the left column. No specific yarn or gauge is given in the patterns. Patterns are available in several languages.
