Re: Simply Summer
This entry: http://shirt.woot.com/Derby/Entry.aspx?id=16573 will be rejected because they're a week late on the slogans derby, but it shows the printable area very clearly.
If you re-sub with your same design but changed so you have it all within that area, it will stand a better chance of not being rejected. It hasn't been rejected yet, but they're pretty strict about "coloring inside the lines", so to speak, and they do go through the submissions more than once looking for things that don't follow the rules.
Other than that, it's a beautiful design! I'll bet if you re-submit it with the print area corrected, people would re-vote for it.
