Hand Embroidery Guide for Beginners – Needle and Threads 101. How many strands of embroidery floss should I use on my project? In craft embroidery today, it is quite common to embroider with all six strands in the needle at once. This creates that chunky, cute style of embroidery that’s very popular right now. If you want to refine your embroidery and manage more detail with finer stitches, you can decrease the number of strands until you find the weight that looks right with whatever you’re planning to stitch. If you want a bold line that can still manage decent detail, start with three strands. If you want a finer line that’s still easily visible, try two strands. If you want a very fine line for delicate detail, one strand will do it! Which needle do I use for my sewing project? All three needles come in a range of sizes where the higher the number, the thinner or smaller the needle. Depending on the size of floss being used, the correct size needle can be used to create the appropriate stitch and leave a minimum size hole once you move the needle through the fabric.
