Wheat-Free "Wheatbags"

Wendy from Matua

Gluten-free heat-bags for those allergic to wheat.
I am going to be making long bags & round bags which can either be kept in the freezer or heated (usually in a microwave)
They will have alternative filling to wheat.
My daughter is wheat intolerant -as are gluten intolerant folk.
Her allergies were exacerbated by others in the house using wheat bags as once heated they diffuse wheat into the air, so I started trying out different alternative fillings and
have found one type of legume to be the most comfortable and holds heat much longer than wheat, without the pungent smell that wheat bags develop
I will be using natural 100% cotton corduroy fabric.
I am wondering if there are sufficient people interested in this concept of heat-bags for it to be worth making some?
They would come with instructions

Heated, wheat bags work by encouraging blood flow to pump around the localized area in pain. A wheat bag can hold its heat very well through the incredible insulated effects of the individual wheat grains. After being heated, the wheat bag stays hot for a long amount of time, especially if it’s in contact with your body. The heat increases blood-flow to the area, revitalizing it and repairing it healthily. 

Depending on size they would be $30-40
(the legume is twice as expensive as wheat, but lasts years)
I have gathered a large collection of corduroy in many colours & plenty of designs, some for kids and masculine options as well.
Can add herbs like lavender, thyme, rose petals, basil or rosemary for their aromatherapy properties for no extra cost 8)
