Making Rugs from Scrap Fabrics and T-Shirts?

I was wondering if anyone has directions for creating a rug from fabric scraps? I prefer one that involves sewing rather than crocheting. I have seen a few tutorials online, but wanted to "pick the brains" of the Thriftyfun community before committing to a certain method. I like the look of a shag (shaggy) type rug. I am also interested in rugs made from t-shirts. Thanks in advance!
