Off the top of my head is the free pattern by verypurpleperson.co
m that she recently did. jcarolinecreative.c
om has a hobo bag tutorial and according to the end of the tutorial, you can sell what you make from the pattern. Another one is the person who did the tutorial for The Lindie Bag (google it)...I'm pretty sure that one is okay to sell if you make it. And according to the terms of use on Burdastyle.com, those patterns that are considered "open source sewing patterns" can be "used without restrictions".
That said, there's a difference between using someone's pattern (even if it's okay to sell what you make from it) and going around saying you designed it yourself and it's "your" pattern. I think everyone likes a little credit now and then.
And I agree with the above posters. Eventually, it's just easier to do your own patterns.
