Oops, I forgot about this post. Better late than never.
Each sample has been felted onto cotton and batting and includes a strand of un needlefeted yarn to the extreme right of each picture.
Yarn and Roving
Above is a simple sample of yarn. This was a very soft yarn and felted easily. Most yarns will needle felt on the machine quite easily, irrespective of the fibre type. Some keep their shape like this, whilst some like wools can lose their shape, but both effects are useful.
This yarn has a nub in it and like most yarns, it felts extremely well. The nubs are good for giving colour in a small area.
This slub type yarn also has a metallic woven in. I often do this myself with a bit of slub, to attach metallic or other non-felting threads. The metallic also adds a bit more twist to the slub and gives it more of a yarn shape although when you look carefully, you can see that the red fibres themselves are not twisted much at all.
I hope you have enjoyed this series on Machine Needlefelting Fibre Samples. I will be continuing in a few weeks with fabric samples.
