My mother once told me that she loved fabric and loved to buy it - but realized she didn't like to sew. (Guess it was passed to me by my great grandmother.) So she gave me the fabric and I have used it to make things for grandchildren and great grandchildren.
I LOVE Christmas fabric and Halloween fabric - I see it and just can't resist. I have over 150 Christmas fabrics and over 80 Halloween and Thanksgiving fabrics. So every few years I make patchwork quilts. Just cut off 2 to 4 squares of each and when I have enough I sew them into strips and into a quilt. I have also done it with hexagons and triangles. It amazed me how much the kids like them because of the variety and I love them because I love the fabrics. Are they color coordinated? No - but no one cares, they are just bright and fun.
Just enjoy the fabric, and keep it for yourself.
