42 gauge triangle felting needles are an extra-fine needle used for finishing, fine detail, and surface polishing — the go-to needle for the final stages of any project. This listing is a 100 needle wholesale pack — our best per-needle value, ideal for studios, teachers, and anyone who uses these needles regularly.

The 42 gauge moves very little fiber per punch, giving you exceptional control at the surface. It leaves an exceptionally smooth finish with nearly invisible puncture marks, making it the standard finishing needle for professional-quality results. It works best on already-compacted wool and is not suitable for early or mid-stage work.

Key Uses:

• Fine detail and delicate surface work
• Final finishing and polishing
• Adding small features and refined textures
• Smoothing and evening the outermost surface layer

When to Use It:

42 gauge triangle needles are used at the very end of a project, when you want to smooth the surface, add fine detail, or polish the finish. Use a 40 gauge first to prepare the surface.

Needle Details:

• Type: Triangle — 3 sides for consistent, balanced felting
• Gauge: 42 — extra-fine
• Barbs: 3 total (1 per side) for minimal, precise fiber movement

About Felting Needles

Felting needles come in a wide range of configurations — different gauges, shaft shapes, barb counts, and point styles. These variations let you choose the right tool for each stage of your project. Originally manufactured for industrial textile machinery, they have been adapted by artists and craftspeople into the hand tools used in needle felting today.
