If you haven’t checked out pattern-collections.com, it’s worth a close look. Many of these tangle patterns are on tanglepatterns.com, but there are some new ones too, and what’s fun about this site is that they are organized in several ways. Want a grid pattern? A simple pattern? One by a particular author? You can find categories that will help narrow your search. The stepouts are colourful and the whole site has a fun, playful feel to it.
And if you are looking for patterns with a Steampunk feel, you owe it to yourself to check out Steampunk Week under Writeups (they are available by Framework also). There is a special Focus section; one area dedicated to authors, one to patterns, and a weekly string collection.
Tons to see, and a great resource, whether you’re looking up a forgotten tangle, or you want to challenge your tangle practise.
