Maybe a Folksy seller knows someone who designs apps?
No, I've had this problem too, trying to find my own shop!
I've always wondered why Folksy didn't have an app like Etsy! Of course cost! It does sound like a good idea crowd funding though!
I have both Etsy apps and would find that I would probably sell on Folksy more if there was an app for sellers (and for buyers too). I would prefer to use Folksy as they are UK based and help support them, but it does make it difficult without an app. Plus, they are getting left behind tech wise!!!
