Crochet Thread Basics

Crochet thread is a thinner alternative to regular yarn. Most of it is made from cotton or blends containing cotton; some may also include acrylic. It can be used for all kinds of projects, including tablecloths, doilies, and accessories like scarves, and hats.

Crochet thread may be used for lacy looks using patterns that call for lace or the mesh stitch methods. Crochet thread can also be useful for edging other fabrics or small details on a garment with finer features than those achieved by worsted weight yarns. Crochet thread may also be used to make tiny motifs such as flowers and hearts for use in crafting projects like greeting cards or scrapbooks.

Thread crochet is similar to yarn crochet in most ways. Thread crochet can be a little puzzling for a crafter who has only worked with yarn because of the minor variances between the two. One of the most important distinctions to grasp in order to master the skill of thread crochet is that the size of the thread and the size of the hook are different than yarn crochet.

Understanding Thread Sizes

Crochet thread comes in sizes 3 through 100. Some of these sizes can be close to traditional yarn and some are closer to sewing thread. One of the most crucial things to remember with crochet thread is that the higher the number, the thinner the thread. This is the opposite of traditional yarn sizing where as when the number goes up so does the size of the yarn. For example, size 20 is much thinner than size 3 or 10. This can trick the mind a bit, but once you get the hang of it you'll be okay.

Some of the most common thread sizes are sizes 3, 5, 10, 20, and 30. Sizes 3 and 5 crochet thread can be comparable in thickness to a lightweight yarn. These are often the easiest to start with when transitioning to crochet thread. Sizes 20 or 30 might be best to save for when you've honed your crochet thread talents. 

Thread sizes are fairly universal from brand to brand except for Pearl thread. This type of thread has a unique numbering system. The thread is softer, glossier, and almost silk-like. This type of thread is available in sizes 3, 5, and 8. If a pattern calls for pearl thread you will want to use this type to ensure the correct size for the finished product.

How to Make Sure the Hook and Thread are the Correct Size

Just like traditional crochet, make sure to check the gauge before starting any pattern. Gauge swatches can be utilized and compared to the pattern's requirements. Start with the suggested hook and thread sizes and make adjustments as needed. 

If you find that your gauge swatch is larger than the pattern calls for, try using a smaller hook or a thinner thread. If you find that it is smaller, try using a larger hook or a thicker thread.
