We're on our way to our friends at Purl Soho. They were super friendly when we were asking about materials, colors, and helps for creating the felties. They were interested in the final results, so we're going to reply.
There might be a change with the hanging loop. We like the same color strand, but may find a better and thinner solution.
In addition, we've made some good ways at La Casita Yarn Shop Café. Folks kinda went crazy (in a good way) when they saw the felties. They have loads of yarn in massive amounts and tucked away in the back is a counter with quiches and empanadas (I preferred the spinach). We hope to maintain a good relationship with them as they are a great community craft provider.
