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. You can also look for the Craft Yarn Council symbol, with crochet thread normally having the 0 symbol (lace weights will also normally be classed as 0, but thicker lace yarns be classed under the 1 symbol too).

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 crochet 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.

DMC Petra crochet thread

The Petra range from DMC is a fantastic sturdy cotton crochet thread, and one that uses the crochet thread number system mentioned earlier to designate slight differences in thickness, including size 3, 5 and 8. This hard-wearing cotton is mercerised, giving it that slight shiny lustre and making it feel smooth and silky. It's also made from long-staple cotton fibres, which essentially means less fibre ends and stronger threads, which not only gives you extra strength but will also help to prevent it from fraying or your final fabric from pilling (creating those bobbles that appear after washing). It's available in a range of 40 solid colours, and DMC also produce many other fantastic crochet thread yarns such as their Babylo, Cebilia and Cordonnet ranges.
