Are you looking to find out what patterns have just been published on Ravelry? I ran across this link just the other day. Log into Ravelry.com (it’s a free membership if you don’t already belong to this awesome knitting and crocheting community). Click on the Patterns tab and on the left side, a little ways down the Recently Added Patterns section. There are thumbnail photos for all the patterns and there is a link that will allow you to do an advanced search and set certain filters for just hats, let’s say.
