A decorative stitch in embroidery made by winding the thread several times round the needle before sewing a backstitch. Short bullion stitches are sometimes called bullion knots.
Also known as, caterpillar stitch ,coil stitch, grub knot, Porto Rico rose, post stitch or worm stitch. You can use wide variety of threads for this stitch, with thicker threads resulting in larger knots.
People either love or hate bullion knots but my love is always for it. Bullion knots suddenly become easier by using a straw or milliner's needle .Bullions worked in rayon are an important part of brazillian embroidery.You can also make hand embroidered bullion roses.
Insert the needle a short space away pointed towards the place that the thread emerges from the fabric. The distance between these two points determines the length of the knot.
Now wrap the thread around the needle as many times as required. The length of coil and the fabric bite should be equal.
Keep the thread quite tight around the needle by holding within your thump and middle finger,
Gently pull the needle pointing outwards from you.
Complete the knot by taking the needle back at the end of the stitch.
You can smoothen the texture by arranging the coils with your thumb
