You don't need to start a whole new account - the page won't link back to your personal profile unless you set your admin status 'live' and viewable. But you do need a personal account to start a page so it's easiest to use the one you have now. You can also set up a storefront using free apps so people can buy straight off the FB page. And an impartial review section, galleries etc etc...
Go for it. It's a nice way to circulate your stuff - every time one of us 'likes' a pic or a post of yours (which we'll clearly do ALL the time
) it'll show up in our news stream so all our friends can see it too - that doesn't necessarily happen with a personal profile. Plus then you can add a FB button to your folksy/etsy shop and your blog and so on.
