What is Tube Yarn? (And How Is It Different from Regular Yarn?)
Tube yarn (often referred to as tubular yarn) is a specialized type of yarn manufactured or constructed differently from traditional spun yarns. It is not spun, you do not need spinning machines to make this yarn. It is a knitted, crocheted or garment fabric constructed to a tube and filled with chosen filling, mostly with polyester.

DIY Tube yarn
As always one of the questions is - what if I want to make one by myself? It is a challenge to DIY tubular yarn. You need a garment and sewing machine, you can sew the tubes, but when you try to stuff it you probably will get bumps in different places and not equal stuffing and imagine that you need to fill at least 100 meters (110 yards). You can also try to crochet the tube, but still adding a plush toy texture with stuffing will be challenging. It’s a huge task, so it is better to use already prepared chunky tube yarn.
Comparison between different tube yarn in a market
You should always check what material is used to produce tube yarn carefully. It is important that the material has an OEKO-TEX certificate. STANDARD 100 by OEKO-TEX—it means that every component of the product has been tested for over 1,000 harmful substances and proven to be safe for human health.
