www.quilterscache.com will give you tons of ideas.
I get a lot of ideas from quilting magazines. There are so many of them available these days. And if you have a Sam's Club membership, they discount magazines 30%. Believe it or not, they carry a couple of quilting magazines!
Oops, I just noticed you're from Australia. I don't know if you have Sam's Clubs there or not. Maybe you have other club stores you can check out. :D
By the way, I love the Australian Patchwork and Quilting magazine.
