The Lana Smartbox Thread Collection from Madeira is an 18-spool set that includes one pack of 110/18 needles, a color card, and an embroidery CD with 30 designs. Lana No. 12 is finely spun 50% wool and 50% acrylic thread that creates wonderfully unique effects in computerized embroidery, serging, quilting, bobbin work, free motion embroidery, couching, and hand embroidery. Try brushing it with a chenille brush to give your design a soft, fluffy, or textured look. With its wool appearance and acrylic strength, you can use this thread on medium and heavy fabrics like wool, linen, and lightweight denim. Each spool features double-locking end caps and contains 220 yards of 30-weight thread. A typical embroidery design has 6,000 stitches, which means each 220-yard Smart Spool with its 40,000 stitches per spool will produce approximately seven designs on average.
