Over-sized tea bags are filled with lavender flower buds, ironed with lavender steam, and sewed closed so they don't open in the dryer.
 
They have multiple uses:
 
Throw one in the clothes dryer the last 10 minutes of the cycle; makes your clothes and the whole house smell great. The same sachet can be used to dry a couple more loads. It would then make great fire starter.

 
Use one sachet to make an entire kettle of lavender tea. Sweeten with honey or simple syrup.

 
Or just place them in drawers, roving, weaving, and knitting baskets to give fresh scent and deter moths.

 
Set one in the dog’s hidey-hole or under the cat’s pillow to deodorize.
