Sisterly - constantly learning here too! I've found that sometimes low prices mean that someone hasn't actually sat down to figure out their costs or used some of the Etsy tools to help. Some might be surprised to see it all on paper and realize just how much time and money goes into creating, listing, and shipping one product from start to finish. I agree though that that can sometimes be frustrating for someone who knows what they need to charge in order to pay themselves fairly for their time & materials, but in my experience I've found that customers will pay more to get more too. It sounds like you're passionate about your products and I'm sure customers will see that as well.
Judith - Blogging definitely isn't for everyone, but if you were to start I'm sure you could put your own spin on things through your unique experiences. For me, my blogs is another creative outlet to write and explain a bit more about my products and ideas, but it's definitely not for everyone :) Anyway, it's more than ok to just read blogs too without writing one!
Thanks again for your comments everyone - I like hearing what other's have learned too.
