I've made a new product that I would like you to let me know what you think. This is my first prototype for my neck pillow. It is 18 inches long. They will be done in different types of lavender, bee, and flower fabrics. After the neck pillow I am going to make eye pillows, and pillow sleeves. They contain around 40% oil, meaning that they can be reheated again and again without losing their ability to retain heat. And have lovely fragrance from the lavender. Other grains contain mostly water that eventually cooks out. The heat is also long lasting - flax seeds keep half their heat even after an hour. Other natural fillers tend to cool down quite quickly. Their small size and smooth shape allows the pillows to contour nicely around your body. There is no cooked smell. When heating other grains like corn and rice, there is a definite cooked food smell. Flax seed has very faint earthy smell that is not very noticeable. With the lavender fragrance most people will not be able to notice it at all. The neck pillow is a sleeve and washable. It has Velcro at the top so the internal flax seed/lavender pillow can be removed when needed. It can be hand washed or put in the washer and dryer on cool settings.
