These sachets are 3 - 4 inches in width and are crocheted with Simply Soft and edged in white You can wash them after the scent is gone and change scents too.. as they are cotton filled. I have scented oils.. Wild Poppy, Grapefruit, Peppermint, Christmas Wreath,Lilac, Jasmine, Apples Cinnamon, Ylang Ylang, Rose, Vanilla, Night Jasmine, Sparkle Shine, and Lavender, . You can also get plain cotton to add your own scent. I will email you to see what scents you want. This would make a nice gift for a friend, coworker, babysitter, mail lady, pet sitter, teacher. I own a cat.. and might have cat hair on them..
