Topstitch needles are typically used for multi-directional quilting, as the longer needle eye is far easier to thread.
Topstitch needles are also good at ensuring fewer skipped stitches - a vital strength for a stitch-heavy project like a quilt.
To get the most out of your topstitch needles, thread 2 threads at once (or use thicker thread) to perform beautiful decorative and topstitching work.
Topstitch needles aren’t just great for quilting - they’re solid all-rounders. Still, the long eye helps it excel especially at quilting and patchwork jobs, or whenever you’re working with thicker thread.
