If you go to the QuiltWorx site there is a link to her Facebook page. I believe there are photos of completed projects from her retreats/classes. I was surprised she didn't have a "Success Stories" segment in her Newsletter. Seems like it would be a great marketing technique for sales.
I have a love/hate relationship with paper piecing. I love how it looks when it's done, but I find it tedious.
If you love the pattern, just go for it!
