Purple Tip Needles are designed to prevent skipped stitches with heavy fabrics, including knits, while doing sewing and embroidery.
Purple Tip Needles are recommended for:
*Embroidery with a high density design and/or thick fabric
*Fluffier thread like cotton
*Quilting multiple layers which normally resist needle penetration
*Sewing knit, tricot, and synthetic fabrics like thick polyester.
