I subscribe to SSW&C. I like to see what's being made and where the trends are. I think they have a pretty good mix of all kinds of scroll work with all different levels of expertise. I think intricate/compicated patterns are hard to describe in an article, which may be the reason you don't see to many. I rarely cut projects from magazines, though. I usually design my own, taking inspiration from magazine projects, stuff others do, stuff at retail stores, etc. That way I can tailor it specifically to my personality. Designing is part of the hobby that makes it fun for me. Others aren't too interested in designing, so they rely on other's designs.
I find books are a great place to find cuttable patterns if you're drawn to a specific type of scrolling; puzzles, compound cutting, wildlife portraits, bowls, etc. If you're drawn to a specific designer's style, you can follow them through newsletters, blogs, and social media. Lots of inspiration there. Forums and social media are good ways to see what others are making. Pattern clearinghouses like scroller ltd, Wooden Teddy Bear, Windfield Collection, etc are good places to browse.
