herb question

[bludog.livejournal.com]

This may seem obvious to some, but I however am at a loss. I want to make a dream pillow and I want to fill it with lavender. I do not grow my own herbs (they always die) so I am wondering where I can get dried lavender from or any other dried herbs really. I was thinking a whole foods market but outside of that I am not sure. Any thoughts, ideas, suggestions? Thanks, and maybe I will try to grow my own herbs again. :)
