What else to do on the train besides blog?

One thing that came out of my practicum today was that I think I have another product idea. I liked the sweater idea, and nothing at all against mrs.halls sister but I think this might be a little better for me considering my schedule for the next month. So, I'm either going to do "The Evolution of a T-shirt" or just taking simple tops and making them my own, and maybe selling them if people like then. But basically, the t shirt idea is that I take like five of the same exact tshirt and make it interesting in five different ways. One with spikes on it, one with an added zipper, one with a sheer back, maybe one with some kind of cool trim...I haven't decided. Or I might just take any kind of simple top and add things to it to make them look awesome. We went into a ton of fabric stores and stores that just sell buttons, studs, trims, and any other thing you might add to any price of clothing. Those stores made me want to start right now. But I'm on the train so I can't just whip out a sewing machine and some trims...and I don't know how to sew...or do any of this stuff actually, so that will be a learning stretch. I've never tried to transform and kind of clothing. I'm really really excited to do this though.
