HOLY SMOKES THAT'S HOT!!!! AND I HAVE THAT FABRIC TOOO!!! GREAT JOB!
Has anyone mentioned yet how hilarious it is that, in one of your photos, your sewing machine is on the bathroom counter?
Seriously, though, I've been looking for ways to modify t-shirts in ways that make sense for a while now. After I made a full-on ballgown with a fairly typical princess bodice, I realized that was just the pattern to use for your technique here. The first one I did was literally about 2 hours before the Buzzcocks show -- used a woven plaid for the sides and some random black tee. Didn't even bother to finish out the hem and the arm holes. But MAN, the difference in how the fit of the shirt LOOKED? Enormous. Princess seams FTW. (And still got my favorite question: "Did you make that?" How much do you love being asked that?)
After I did this second one, I realized another of the cool things about this is that you can use wovens or knits for your side panels -- the "Tractor" tee uses a fairly stretchy knit, as you know cuz you have it! So, really, ANY fabric you've got, what, a half-yard of becomes the perfect detail!
This is going to be my stash-bustin', kickin'-around summer wardrobe staple for 2010, I'm pretty sure.
