  1. From Fluff to Firm Felt What Fulling Does in Wet Felting

    What “Fulling” Means in Wet Felting

    Fulling is the final strengthening and tightening stage of wet felting. It happens after the fibres have already begun to felt together during the initial layout, wetting, and gentle agitation.

    It’s the point where your soft, loose felt transforms into dense, durable, cohesive fabric.

    Guide to Wool Types for 3D Needle Felting

    Choosing the right wool shapes how your sculptures behave under the needle. Some fibres build firm cores quickly, others create smooth outer layers, and some add texture or special effects. This guide breaks down the most common wool types used in 3D needle felting and what each one does best.

  3. Nepps: Tiny Fibres, Big Texture

    Posted on

    What Are Nepps (and What They Actually Do in Felting)

    Nepps are tiny, compact wool pills created during carding. Because the fibres are already tangled into tight little knots, they don’t draft, and they don’t fully integrate into surrounding wool the way regular roving does.

    This is exactly what makes them useful: they sit on the surface of your felt and create texture, speckling, and organic irregularity.
