Powerful and intense, Thunder is the darkest shade in the Shades of Grey Series — a near-black charcoal grey that anchors the full tonal range with serious depth and drama.

This bulky carded Corriedale wool roving is blended from a dominant proportion of black Corriedale fiber with just enough white to keep it from reading as pure black, resulting in a deep, rich charcoal grey with enormous visual weight. The color evokes the sky at the height of a thunderstorm — heavy, saturated, and commanding. Up close in the fiber you can still detect the characteristic salt-and-pepper texture of the blend, which prevents it from looking flat and gives finished work a natural, organic depth that solid black fiber cannot achieve. This is a clean, cool-neutral very dark grey — not blue-black, not brown-black, just an honest near-black charcoal.

Perfect For:

• Needle Felting - deep shadow areas, dark animal coats (bears, ravens, panthers), and bold contrast accents
• Wet Felting - a strong, grounding dark tone for dramatic abstract and landscape pieces
• Spinning - produces a near-black charcoal yarn with subtle natural variation from the fiber blend
• Weaving - a powerful dark neutral that creates bold contrast in any tonal textile

Pro Tip: Essential for the deepest shadow work in felted portraits and animals — use it as the darkest anchor in a full ombre sequence across all five shades of the series.
