My main supplier of natural coloured fleece is Shirley Peddie of Karetu Koloured Wakari, North Canterbury, a specialist breeder of naturally coloured, mostly Romney and Corriedale sheep.
If you are interested in raw fleece, or fleece already carded and gilled, please refer directly to Shirley: email@example.com
If you are interested in her wool handspun, I have a variety of skeins available, and take orders for colours that interest you.
The yarn is aran or 10 ply, slightly textured with a high twist. Knits on 5mm needles with a gauge of 14–16 stitches per 10cm. So mostly suitable for an aran or 10-ply pattern. Check it with a swatch.
Handspun wool has a bulk, lightness and loft that is completely lacking in commercially processed wool yarn. It needs to be knitted on slightly larger needles than commercial wool.
The handspinning process encloses more air and that loft needs to be carried through to the knitted garment.
A garment knitted on handspun wool has three times the life expectancy!
Basically cast on 200 stitches on a long circular needle and knit until the other side of the bd, then cast off!
