I usually make lap size quilts and will easily spend $100 for fabric, batting, and thread. For the amount of time it takes, I find it's worth buying the best quality fabric for quilt projects. If I'm purchasing fabric for a sewing project, where an item will only be worn for a year or two, then I don't mind buying lesser quality fabric on sale. But, for my quilt projects, I expect them to last throughout the years, so I'm less concerned about saving money on the fabric.
