Best crochet thread and crochet lace yarns

If you like your crochet looking fine, then here's some awesome crochet thread and crochet lace yarns for you to check out!


Crochet thread is perfect for intricate crochet projects and is usually worked with a hook size of around 2mm. It can get a little bit confusing at times as it also falls into the same category as lace yarn (which is a term more widely used in the UK, and is more of a general term as it can be used for knitting too), but they’re both roughly the same thickness – usually when people call it crochet thread they’re referring to yarns made from cotton/sturdier fibres. Essentially though, it’s yarn that is thinner than sock/4ply weight yarn… think of it as a similar size as standard embroidery thread.


It’s also important to be aware that especially with yarns defined as crochet thread (or crochet cotton), there can be slight differences in thickness. Some crochet threads will use a special numbering system, where the larger the number, the finer the yarn. For example, a size 3 crochet thread is thicker than a size 20 crochet thread. Roughly speaking a size 3 thread would be closer to a 4ply yarn, whereas a size 10 crochet thread would be more like a lace weight yarn (and a size 20 is going to be incredibly fine). For this reason it’s super-important to do a test swatch when using crochet thread as well as checking the tension guideline on the ball bands/descriptions.

Crochet thread/lace weight yarn can be a bit tricky to use for some crocheters as it’s quite so fine, while others revel in the lightweight fabrics and delicate projects you can make with it. Here’s our pick of 10 fabulous crochet thread and lace yarns for you to try!
