3-Ply…or more

What is a 3-ply yarn? A 3-ply is a yarn with three singles spun together. If the singles were Z-spun, then you will S-ply, and if the singles were S-spun, then you will Z-ply. The same goes for 4-ply or more-ply yarns, just add more plies!

Why use multi-ply yarns?

Pros

• The yarns stand up to abrasion and wear which is great for socks.
• The more rounded structure of the 3-plus-ply yarns make cable and other knit and purl stitch patterns pop.

Cons

• Spinning more singles takes more time.
• Managing more than 3 or 4 plies can take practice and may require more than one lazy kate.

Tips

• Judith MacKenzie suggests spinning all of the singles before you begin to ply.
• Survey singles for consistency.
• Spread inconsistent bits from less than perfect bobbins throughout the whole project while plying to even things out.
