Yarn, of course! My passion is spinning and dyeing my own yarn, so that I have lots to choose from when I knit. Not only wool, sometimes silk, soy, Tencel, even recycled plastic bottle fibre; but mostly wool.
Some of this recently dyed Shetland is my current jersey-in-progress -
This dyed BFL fibre (that's fleece from the Blue Faced Leicester breed of sheep) was spun and knitted up into a big warm shawl -
Most of this yarn, the purple merino and silk, and the tweedy grey mixed wool and silk, are destined for a jacket which is in the planning stage, and may be the next project on the needles -
And this is my current yarn and fibre storage system, 5 folding crates, with associated bags -
And, as the fibre supply is a bit low, an order for more has just been posted - I may need another crate!
