The first new rule I heard when I started Machine Embroidery was that I had to use a thinner bottom line, only white or black. I have a lot of questions about this rule. First, even my husband remembered in his 7th-grade chef and tailoring class that the bobbin thread was wrapped around the spool used for the project. It has the same weight and the same color and produces the best physical and visual impact. If the bottom line is 60-wt. It is much thinner than a 40-weight machine embroidery thread. Even if the machine has a self-adjusting ability, the tension of the embroidery machine must be strictly adjusted. The difference in weight discards the entire embroidery piece. Also, if the bobbin uses a different color, any burrs in the stitch will show significant detail on the top.
When stitching a separate lace embroidery design, many stitches are not satisfied with the finished product. Many of them fall apart rather than hold together correctly, and many of them look awkward and not like beautiful lace. Almost 100% of the time, the culprit of these problems is the use of bobbin thread in the bobbin. Once the stapler tries the same thread on the bobbin and the top, they are completely satisfied with their Machine Embroidery work.
The other two stitches also require the same bobbin thread in the bobbin. The first is the satin stitch. Both of the thinner spools pull too much of the top line to the back of the part and tend to appear at the edges of the satin stitch. If you use a white or black underline in different color satin stitches, the finished embroidery design looks bad. The second type of stitch that requires the same top and bottom threads is red-work. The red embroidery is very close to the regular sewing stitches used to create the seams and hem. The first thing we teach in sewing is to make sure we use the same line at the top and bottom!Another theme that has plagued me in the field of Machine Embroidery is that only those items that are specifically used for machine embroidery can be used. For example, an embroidery stabilizer and a sewing interface are used. Yes, they are called by different names, but it is exactly the same thing. The main difference is that there are more types of interfaces and lower costs. The amount of embroidery stabilizer is small and the cost is high. Of course, there are some special types, such as water-soluble stabilizers for freestanding lace, but all other types can be purchased inexpensively from the interface frame rather than the embroidery aisle.
