What it takes and what it makes...
You can also ply a yarn on itself with Navajo plying, and this is an excellent way to highlight a colorway in the yarn, but it is a triple ply and uses more of the yarn single.
You'll also note that the picture says 'Before Fulling'. This is important, the final step to 'set' your yarn is to wash it and let it hang. With any yarn that includes our favorite fiber~Angora~ we also 'full' it by alternating it in hot soapy and cold rinse baths and giving it a good beating...
As you work with the yarn for your project, it will bring out more and more of the beautiful halo and because of the variation of fibers including wool,
alpaca - that is 4 X's warmer than wool-,
angora - that is 8 X's warmer than wool-,
and silk - also known for it's natural insulating properties;
you have a lofty, warm, one-of-a-kind luxury yarn for that perfect project.
