Ravelry! has a huge pattern data base! It's endless, I swear!
I also faithfully follow the new releases put out by Twist Collective. All of the designs are by different designers! They are all purchased on a pdf basis...so no need to purchase an entire $30 book to get one pattern!
Also, sometimes I look through general categories, like "scarf" for instance. Scarves are like jewelry, you can't own too many scarves...and great for gifting, too!
I also 'follow' several of my favorite designers on Ravely, in their "Group". When she/he has a new design, it will be advertised there in their Group.
For example: BROOKLYN TWEED (Jared Flood). Oh my, he is a talent! He does everything from A to Z...hats, scarves, shawls, garments.
Other favorite designers are:
BABYCOCKTAILS (Thea Colman)
Twist Collectivehas a Groupat Ravelry, too!
One of my Rav BFF's also sends me links to great patterns she has stumbled upon at Ravelry! I frequently get a message from her that just says: Look at this! :teehee: Which I always do...and end up with another pattern in my library!
