Linda, i know exactly what you mean. I like to shorten my t-shirts too, so they're right at the hip. I have a terrible time with knits, as you sew them, they stretch. This is what i was thinking of doing for next time. I think the hem on the shirt helps stabilize it, so the minute you cut that hem off, everything at the bottom just spreads. I am thinking next time, of cutting a long strip of paper, and pinning it to my new hemline, to stabilize it, then sew the hem, then rip off the paper. I think a strip of interfacing could work the same way too.
