Charm Packs are collections of color-coordinated 5" fabric squares. Moda Charm Packs evolved from so-called "Promo Packs" that were used to preview upcoming fabric collections. However, it wasn't long before savvy quilters began using the convenient sets of pre-cut squares in their quilts, and the legendary Charm Pack was born. Charm Packs are now available from a variety of manufacturers and are perfect for any project including quilt tops, fashion apparel, home decor and scrapbooking.
