Instead of cutting it? I hate it when they do that! The edge of the fabric curls...especially if it's not cotton as mine was not today...it pulls down the warp and weft of it somehow and strains it.
Today in the fabric shop in town, I was buying four metres of 4 different fabrics. She took the first roll, measured it and then rrrrrriiiiiiiiiiipppp! 
So I said politely "Would you mind not tearing them please? I'd rather they were cut as the amount I am buying is already tight for the project I have in mind"
And she said "It'll fray anyway...and I'm not very good at cutting so it might not be straight" in a warning kind of voice.
So I said, well as long as I have a fully useable metre I don't mind.
As I went upstairs to the next section, I could feel ALL the eyes of the girls who work there boring into my back.
WIBU?
