Last year's New Year's resolution was not to buy any more fabric until I used up my stash. I must admit that I did buy a small amount of fabric - but over the year I spendt only $45 on fabric every thing else came from the stash. I have to say that using up scraps has actually made my quilting projects better. After all, our ancestors didn't have books, rulers or easy access to fabric and they made outstanding quilts.
Another benefit is frabic from the past rekindles wonderful memories.
