A couple of things that did stick out to me on the site itself...
When you say "hand sewn Ink Drop label" do you really mean hand sewn, as in with a needle and thread? Because either you should look at using a sewing machine, or you're not hand sewing (there's no such thing as hand sewing by machine).
The wood grain sidebar... to me it's played out. Maybe it works for your target customer, I don't know. To me... too clichéd.
Why is 'blog' pluralised in the top bar? As far as I can tell you just have the one (as makes sense).
I'd be concerned about splitting the customer's focus between 'custom' shirt printing, and your product since that's two wholly different markets, different motivations, etc. Still, it seems to be a new area for you and it's going to be hard to work out how to best capitalise on both markets. I get that. Long term, I think you want to split those to different sites though.
Is your site running on Wordpress? You don't need RSS links on every page, I'd ditch them if possible.
Fix your Facebook link; the one next to the twitter icon and RSS icon is set to the longform of the URL, when you have registered the short form of the URL.
I like your logo. It's bold and simple, as a logo should be.
I like that you've narrowed down your target market. You now know who they are and why they want your product. You know what to design, why you're designing it, and who you're selling to. Very important stuff that very few people get right. You have - well done.
I'd go over your copy and tighten it up a bit, or get someone else to do it if you need an outside perspective. One example: on your 'About' page, don't blame the town for your business failing. Whether it's true or not it looks petty, and whether it's true or not it's your fault for opening a store in an economic downturn in a place with the wrong demographic and failing to market it. Own up to your mistakes or avoid mentioning them, but don't blame them on other people. In this specific case... you certainly don't want to say "we messed up", but find a better way to say you had a store and no longer do than "the world just wasn't ready for us man! we're too radical and/or good". It's a crap cliché.
Your current front page graphic about the sale is boring. It's a huge visual, the main first impression of your website, and it's not doing anything interesting - wasted opportunity. You have better graphics and better photography already -- the fact that it's your area shows -- so you could be better using them to your advantage.
Your presentation is professional, which is important (obviously).
In general, it's good. I'd say you're off to a good start. Just keep fine tuning and learn what works from paying attention to your customers.
