Indiemade stores don't have www in front of them. I don't know the technical reason but it's just how the URLs are set up. What most people do is buy their own domain name - in your case FeltedFriends.com and have it redirect to the site so they don't even use the Indiemade domain. That's something you can do later if you decide to move forward.
As for Google, that just takes a little time and content. Once you're happy with the site, go here:
https://www.google.com/search?q=submit+url+to+google and submit your URL. That will help kickstart the Google indexing. But just know that indexing can take a few weeks. If you update regularly with a blog post or news, that will help Google find you faster. There are other SEO techniques - we can help with all of that if you join our Facebook group
