Crochet with embroidery thread usually refers to perle cotton or similar twisted embroidery threads, a step up in thickness from six-strand floss and easier to work with a slightly larger steel hook. I switched from floss to perle cotton for anything larger than jewelry scale, since the thicker single strand holds tension more predictably. This guide compares the two and covers hook sizing.

Thread vs. Floss
Six-strand floss must be split or combined by hand, while perle cotton comes as a single twisted strand ready to use straight from the skein, making it faster to start with and more consistent stitch to stitch.
Hook Sizing
Perle cotton in a common size 5 or size 8 weight typically pairs with a 1.5mm to 2.0mm steel hook, slightly larger than what pure floss needs. Always check the specific thread’s recommended hook size on the label, since numbering systems vary between brands.
