For the purposes of spinning, it is applied to multi-coloured tops where we split the top into ever smaller lengths. There are, of course, variations on the main idea, and these can also be applied to any series whether, tops, fleece or textures.
I chose these beautiful silk tops, of which I only had 10grams. Enough to finish in a short time. I split them down the middle and spun the first half as it came from the top. I did a little pulling apart to try and maintain some blocks of colour, but I wasn't very precise or finicky. This was my first bobbin.
The second bobbin, I split the remainder of the top and spun half, and, continued splitting in this way until I wasn't drafting when I was spinning. I managed to split it four times (five lengths). I wasn't sure of the result, as at times, the second bobbin seemed quite different, but then at the end I couldn't really tell them apart!
