So I want to start selling my handmade fingerboard decks. But what is the best way to ship fingerboards? Do stamps work fine? If so how many stamps? 3-4? On just a normal envelope?
And I was thinking about the price It would be anywhere from $10-$20 if i sold them for 10 it would not include shipping. If i sold it for 15-20 it would be shipped. What do you guys think?

when i ship a deck out, it is usually around 3$ in a bubble mailer. Im not sure about stamp wise. I just take it to UPS, but I'm sure someone here has a better solution.

For the prices of the deck, look at some of the companies in the company section and see what prices they charge. Try and charge around about the same price as a company of whose standards you feel equal the standards of your own decks. As for shipping, i used to just take mine to the post office and they would do it, but try googling how many stamps needed for a ______ sized package, weighing ____

yeah take it to the post office and get it weighed. If you just put a stamp on it it might not be enough and then the person receiving the package will have to pay the difference.

Bubble mailer. Just address it and take it to the post office. They'll do the rest. Usually takes like $2-3 to ship a bubble mailer. Depends what it weighs and all but yeah.
