I make lavender eye pillows. They are very popular and easy to make. Make a approx 4 1/2 inch by 11 inch sack and fill it about 1/2 full- I use a cup of flax seeds and 1/2 cup lavender buds. They smell divine and are very helpful for people who get migraines or just need rest. I've made them for wedding parties, mothers to be, mothers with newborns, etc.
I sell them as a fundraiser for my dog rescue. $10.00 a piece and they sell! (The scent draws in buyers- have a couple on hand for "testers"- let people lean back and put it over their eyes.)
You can get lavender buds online fairly inexpensively. i use perfume grade rather than "craft" grade, as it often is old and has no scent. And I buy flax either online wholesale or at Wild Oats in bulk.
