I didn't read all the responses so I hope I am not being redundant but... when I was an uninformed consumer (ie. before I started to quilt), I was more impressed with a quilt or other items when there was a well written description of it.
For example, queen sized charm quilt using the tumbling blocks pattern. Constructed with 750 different pieces of high quality fabric. 100% cotton and machine quilted with curly loops and feathers. 75 hours of love and labor to construct this custom quilt. Can be displayed on a wall, draped on corner of sofa or used to warm a full or queen sized bed.
You can also add the name of the fabric collection you used. Think about how paint companies name their paint colors instead of just numbering them. sometimes we are drawn to the name of something. I painted my walls a decade ago and still remember the color is "filtered sunlight."
Type the description using a large decorative font, too.
Good luck with your raffle.
