I have an Etsy shop and believe anything can be profitable if you have a niche. I started doing one thing then moved to another and have fine tuned my offerings by listening to my customers. What I do is definitely a saturated market, but my customers wanted something bigger than most can offer, so I bought equipment I needed and offer what I do in larger sizes. Each year is better than the one before.
I use Paper and Spark products and they are awesome.
