Needles
Felting needles are available in a range of gauges and shapes with a different number and placement of notches up the shaft, making them suitable for different kinds of felting. I’ve listed the ones I use most below and will continue to add a few more. Handle all your needles with care, especially the finer ones. When you are felting, keep your stabbing motion straight (at whatever angle you are working); needles snap when you insert and bend. If you are working with a wire armature, you’ll also need to take care not to hit the wire. All of this gets easier with practise and becomes more intuitive. Take care not to poke yourself (those needles are sharp!). Use a gentle, quick stabbing motion, close together. For shaping, the needle goes in a little further than for surface details. In general, you’re only using the bottom 1/4-1/3 of the needle.
Gauges: The most commonly used gauges run from 36-42; the higher the number the finer gauge, and correspondingly, they are generally used for finer fibres and finishing surfaces.
36 gauge needles are great for starting to build up your core wool and for shaping and sculpting later on.
38 are slightly finer and are good for when you start to go in and shape your wool, working the surface so it is smoother.
40-42 are quite fine and are good for working with finer fibres and surface details. The best thing to do is just play and experiment with a variety of needles (and keep a notebook of which one you like best for what!).
You can use multi needle tools. I tend to use a single needle, unless I am working on a larger flat surface. But see what works for you. For flat surface surface detail, a 5 needle tool is good, whereas for sculpting, a 2-3 needle tool is what you want to be using (unless, like me, you prefer a single needle).
40 gauge / 2x2x2 barbs / 3 inches
Orange Wizpick is a great finishing needle for all fibres, especially fine ones such as merino and silk. It leaves fewer marks and a smoother finish. I use this to finish eyes, and felt smooth layers of merino on bodies and faces.
40 gauge / 2x2x2 barbs / 3.5 inches
Cream Wizpick is good for early and firming stages of felting for fine wools, or for fast, deep action with easy penetration on medium wool. The Cream needle works particularly well for Merino when other needles seem to not grip the fibre. This needle is delicate and tends to bend easily. It’s good for smoothing surfaces. I sometimes use this on the core wool to help flatten and smooth.
42 gauge / 2x2x2 barbs / 3 inch
White Wizpick are for working with fine wools such as merino, and other delicate fibres like silk rovings. This needle bends and breaks easily, so take care when felting. I use it for the same things as the orange.
32 gauge / 8x0x0 barbs / 3 inch
Blue is a good needle for fusing pieces together.
36 gauge / 2x2x2x2 barbs / 3 inches / star
Red Wizpick is great for medium and coarse wool. It’s a star needles, which means it has four sides and high barb density, but it still penetrates firm felt easily. It’s an excellent sculpting needle and one of my go-to needles for any project I do when building up the body.
40 gauge / 3x3x3
Spiral felting needlers help speed up the felting process. The barbs are arranged in a spiral on the tip. Every time you press the needle into the wool, it not only hooks them together with the barbs, but it also slightly twists them -- making your felt shape and harden faster.
The spiral needle leaves fewer marks on your felted surface. Use these needles in multi-needle holders to have a powerful tool for speedy felting.
