As you stitch cross stitches, the floss tends to twist and eventually knot. The simple solution is to frequently dangle the needle and floss allowing it to untwist. Once you get into a routine, you will do this without thinking. Until you do, consciously take this step every few stitches.

Embroidery needles used for cross-stitch are often called cross stitch needles or tapestry needles.
Cross stitch needles come in different sizes depending on thickness. Most commonly used size is 24. It is the best choice for stitching on 14-count aida.
A tapestry needle is a hand sewing needle with a blunt end and a large eye.
You don't need a sharp needle to use with an open weave like Aida.
The rounded tip of a tapestry needle is important because it helps to ensure you don't accidentally pierce the threads of the fabric.
