Mum and Dad have just returned from some touring. Poor Dad, he's not allowed to go past a fabric shop. Their trips and stopovers are pretty much mapped out according to which towns have quilting shops. Anyway, today Mum was horrified when she purchased some fabric and the assistant/shop owner ripped the fabric she wanted to buy. After the first rip she said she preferred her fabric cut...so the lady allowed an extra 1 cm and continued to rip the next piece. She's decided not to return to that particular shop.
I've had a bit of a read on the subject and I realise ripping goes accurately along the grain but you do lose a portion along the rip where its all skewed. Some shops state on their web sites that they allow for this.
I prefer my fabric rotary cut too.
How about you?
