I was introduced to eye pillows when I started getting migraines – they are useful at blocking light and can be relaxing when scented. Eye pillows are filled with flaxseed, and can be heated in the microwave (40-60 seconds) or chilled in the freezer (put in a freezer bag so that they don't soak up food smells).
I can make your pillow unscented or scented with lavender, chamomile, or peppermint. If you have a particular scent that you like, let me know, and I will see if I can find it for you. Pillows with covers are $12, pillows without covers are $10.
