Heather,

Part time or full time, you should still go through the steps I recommended so you go into this business with your eyes open. You'll have a better handle on the viability of the business, the pitfalls, and what you need to do from a legal and tax standpoint.

I have no idea what an Etsy store is.

As for paper merchants, these are authorized mill agents (distributors) for the various brands, and as wholesale stockhouses, can work with you to get you what you need, when you need it. They can also make recommendations for your needs, and provide samples and swatch books. They carry full lines, grades, weights and colors for the papermills they represent. As paper is heavy, and shipping cost is based upon weight, bulk, and distance, ideally you want to deal with merchants in your area.

If you find a particular stock you like, you can contact the papermill and ask who are the agents in your area. Many are designer-friendly and can also supply samples and swatchbooks at no charge.

Note that you will have minimum shipping orders when ordering wholesale -- but it is a lot cheaper than buying from a storefront retailer.
