We have tried: When embroidering, specific loops are formed on the front side of the pattern and the embroidery has a plastic impression. We used embroidery hoop 780657, fabric (in our case jute 380530), suitable yarn (e.g. 290410) and a hollow needle, which looks like a pen with a sharp tip, in which there is a hole through which we pass the yarn with a special threader. The threader is included in the package. We redrew the prepared pattern onto the fabric, which we clamped firmly into the embroidery hoop. First, we embroidered the outline of the pattern and then, gradually piercing the fabric stitch by stitch, the inner surface of the pattern. When working, it is important to keep the needle perpendicular to the fabric, regularity - the stitch next to each other and the looseness of the yarn (the slightest tension of the yarn will cause the loops to pull out of the fabric). With this technique, we always work on the back side of the pattern (from the wrong side). Loops are created on the front side of the pattern. After completing the embroidery, we fixed the pattern on the reverse side with non-woven iron-on fabric 350357. Working with a hollow needle is very fast and simple.
