I've managed to take some photos of some spun skeins of my new Heather Silk.
As ever, with this style of blended fibres taking photos is rather tricky, because the multi-tonal effect really plays tricks with the camera sensors. Add in the high shine you get from mulberry silk, and you end up with a very large number of rejected photos!
For each colourway I spun 2 different samples. One was spun using my normal silk draft. Straight from the end , with a moderate degree of twist, and then plied to balance. It creates a smooth, very shiny yarn with excellent drape, and huge amounts of lustre. The other sample was spun using the style advocated by Sara Lamb (author of The Practical Spinners Guide- Silk). This sample was spun from the fold, using small chunks of fibre, with as much twist as I could bear to put it, and then plied with lots and lots of twist. This yarn will be harder wearing, more resistant to abrasion, but isn't quite so shiny, and doesn't drape quote as well.
If you'd like to know more about twist levels in silk then I wrote an article for the Fine edition of Ply magazine a few years ago, and also shared some close up photos on the blog.
If you prefer videos over words, then this video, filmed for last months Non-Wool Club should help.
In addition to effecting the structure of the yarn, the spinning technique also has an effect on the colour. The silk is made up of lots of very thin streaks of different colours .
When you draft straight from the end of the fibre you draft in fibres from multiple streaks of colour. When you draft from the fold you sometimes end up pulling in fibres from just one colour. Spinning from the end produces a yarn where the colours are more blended together, as the act of drafting carries on the blending process. Spinning from the fold produces a yarn where you get more flecks of yarn that are only a single colour.
In the photos below the yarn on the left was spun from the fold, the yarn on the right was spun from the end.
Hopefully if you've been wondering about how this fibre spins that might help answer some of your questions, and help with your design making process if you've already bought some of this fibre.
