Some Flaxseed pillows makers are advertising their pillows as 100% Organic when only the herbs but not the pillow fabric is Organic. Cotton is actually the dirtiest crop in terms of pesticide use, so if the pillow fabric is not Organic, the whole pillow is definitely not Organic. If you really want an Organic pillow, you don't want the part of the pillow exposed to your skin to have carcinogens or hormone disrupting chemicals.
Flaxseed neck pillow line made from all Organic cotton or pesticide free hemp. Thanks to the soil association for this helpful infographic that explains why Organic cotton is so different from non-Organic cotton. To keep the price down on our pillows we started reselling some of the Organic cotton fabrics in our Etsy and Ebay stores, so check them out if you sew; we have flannels, poplins, bark cloth and corduroy.
