Hi Lisa,
I took a look. I like the colors and photos -really nice.
If I had to pick something, I guess I would suggest:
1. Try to shorten the verbage. There is alot of writing, which means alot of reading. When I see that, I usually will skim the paragraph and in the process, will miss information. If you weed out the most important stuff for me, then I won't miss the *message* you are trying to get across. Laying info out in a way that's easy to absorb helps me read faster, makes the page more interesting and varied, too, imo.
Like for example, the paragraph that highlights occasions that are great for tees is a longer paragraph, and the word custom is repeated.
I can read something like this:
Event and Celebration Custom T-shirts:
* Family reunions
* School reunions
* Weddings
* Bachelorette and Bachelor Parties
* Birthdays
* Halloween
* Patriotism
* Valentine's Day
* New Year's Eve
* Anniversaries (I added that one

)
Corporate Custom T-shirts:
* Company Promotional Shirts
* Company Picnics (just an idea)
* Customer Appreciation (just an idea to beef this section up)
Faster than I can read something like this:
(I just copy/pasted from the site if that's okay)

*****************
Maybe focus on condensing the information to as little as possible, a little more than "bullets" - while still getting the important meaning across.
If I am shopping for something, I am usually shopping a few sites for it. I am gathering information, so the less "extras" I have to read thru, the better for you (I'll stay on the site) and me, I get thru the info fast and onto doing what I am there to do "SHOP".
**The second thing that would enhance the site would be to get the width more narrow as it flows past the viewable screen on my monitor. It's usually a bother to me to not be able to see the "entire screen" and have to use the scroll bar to move side to side.
Good luck, all this jabberjawing is only an effort to help enhance the site, not to knock it in anyway. If you changed nothing, you'd do fine, it looks good, but if I had to choose something, it would be organize the words to be more bullet-like, more efficient to get thru the reading part, and to narrow the site settings. Best of luck to you and .....
