These little sample show straight stitch with equal tension as the thread is the same in the bobbin, in this case Isacord 40 which is a very fine thread used for machine embroidery. The result is a very fine and detailed stitch. In samples m to o the stitch density has been indreased .
samples q to y have been done with a free machine zigzag stitch. Although a hoop was used to stretch the fabric, this did some puckering which creates additional texture.
For these samples two contrasting threads where used: the blue Isacord and in the bobbin a Gütermann Polyester sewing thread. The upper tension was adjusted to bring the bobbing thread to the surface of the fabric. With fine thread like these two a very subtle effect is achieved which might be difficult to see in the pics above.
Samples m to p show free motion zigzag stitching, especially where I changed direction in the stitching the bobbin thread is pulled to the surface of the fabric.
The next two samples show a little experiment where I tried to see how a nylon thread would look like with a colored bobbing thread. I love the effect of the little dots created with this technique. I also think that the texture created by the stitching becomes more visible. I certainly will try to work with nylon thread both as upper thread and in the bobbing on water soluble fabric.
3C: Cable Stitch
This technique put a lot of strain on my sewing machine and showed that it would take threads only up to a certain thickness. Every thread that is thicker than a strong perlé thread is difficult to work in that sense that it wouldn't fit through the bobbin guide. Although sample "w" looks quite interesting, it is not successful as I would have had to adjust the upper tension accordingly. On these three samples I tried to use a thicker thread (Madeira Lana) as the upper thread, but you loose the "effect" of the bobbin thread, in that sense that the thickness as well as the color are to strong and somehow "cover" the decorative thread used in the bobbin.
Adjusting the upper thread tension accordingly for every combination of upper and bobbin thread is essential here as well as doing some sampling
Nevertheless, I think this is the best way to achieve texture in machine stitching and I look forward to combining the 3 different techniques, although means a lot of thread changing.
