Yeah what Bree said.
Definitely contact the designer.
Our storewide TOU states that even for s4h, each item you sell must be completely custom (not just changing out the name or photos). It's my understanding that people typically use the same basic design over and over for siggies, no? (I'll admit I really know nothing about siggies).
But also, some of the designers don't allow their products to be used commercially online (etsy, blogs, etc). So, I'd definitely just contact the individual designer and clarify where she stands. We all get these questions all the time, so it just takes a moment for us to respond.
