I agree that using PappaShoppe and getting a cheap design tempelate is the way to go. It's really easy to maintain and the start-up cost are very inexpensive. I would def suggest etsy over ebay. Even talking to clients I find that people think of ebay as more of a bargin shopping network vs esty as a place to find amazing hand-made items. Just my 2-cents. Had I known about etsy first I would have waited to get my website
Your flip flops are amazing by the way! I'm hosting a flip flop party in 2weeks

I'm excited and nervous all at the same time..
Good luck, and if you ever need any techie advice let me know
