Straw
The Herbs

Powers: Luck, Image Magic

Magical Uses: Straw is lucky; hence it is often carried in small bags. For a home luck talisman, take a used horseshoe and some straw, sew up into a small bag, and place it above or below the bed.

Small magical images may be made of straw and these can then be used as poppets. Straw attracts fairies (some say that fairies live inside straws).
