I'm a big fan of do-it-yourself fashions, especially t-shirt deconstruction and stencils.
So when I first joined the crafty Livejournal communities of StencilCry and Stencilxcore, I was excited to see cool designs coming from kids who wanted to do something different with the shirts they found in the store.

I was even more thrilled when I saw some truly original and fun Star Wars shirts come out of the community like the ones here:

Boba shirt
Han with Movie Titles shirt
Sith Happens shirt
X-wing shirt

It's not too hard to make shirts using designs you make yourself.
(Just don't sell them or that would be a no-no.)
