Oh, by all means use them and enjoy the beauty that you created!!
Some years ago I made a quilt for a young couple out of her wedding dress. It was going to be used when they had their first child. They used it once for her christening and once again for the christening of her sister a few years later and since it has been stored away in a closet. So sad. She said it was too special to use.
I told her that I threw that dress into the washer and dryer before I started to cut it so it can be washed. Since it is satin and was slippery to sew I double sewed the seams and so it's reinforced and strong. It was meant to be used and loved as all quilts are.
