Hi Brenda,
Exactly what you said. We see something we like and don't want to miss it so we buy it. Also most of us find it hard to resist a bargain or a fabric sale. How much, is a personal choice.
Don't forget to check out the classifieds here. I've bought from several ladies and have been very happy with the price and top quality of the fabrics.
