Be sure to not use more than the manufacturer's recommended amount of fragrance oils. And DO NOT go crazy if you are using essential oils, they can be very dangerous and the way people without any real training (aka Multi Level Marketing) are selling them these days I think many people overuse them and use them in ways not intended.
Thanks, glad you like it! If you like the fabric, you should totally check out other fabrics and artwork by Laura Gunn (I am lusting after some of her canvas artwork, my absolute favorite designer!) I have one more panel left after this project and have to think up something perfect to use it on.
A quilt needs a top, middle and back and the 3 layers need to be connected some way (quilted or tied). I think that's all! Of course, you could make the case for a light summer weight quilt without any batting as well. It doesn't necessarily even have to have a pieced top, whole cloth quilts are a thing!
