Cotton requires a moderate tension setting, usually between three and four.
What should my thread tension be set at?
So we’ll be talking only about the top thread tension since that’s where you’d usually make the adjustments. The dial settings run from 0 to 9, so 4.5 is generally the ‘default’ position for normal straight-stitch sewing. This should be suitable for most fabrics.
What tension should I use to sew thick fabric?
The thicker the fabric, higher the tension must be to lift the lower thread up to the middle of the layers of fabric. You will usually be alright with a 4 or 5 on medium to medium-heavy fabrics like linen and twill weaves such as drill and denim.
What is the average tension on a sewing machine?
Most sewing machines will have the standard tension marked with a dot or line. My machine averages out at 4, and I usually don’t have to adjust it too much from there.
Why is my thread bunching underneath?
A: Looping on the underside, or back of the fabric, means the top tension is too loose compared to the bobbin tension, so the bobbin thread is pulling too much top thread underneath. By tightening the top tension, the loops will stop, but the added tension may cause breakage, especially with sensitive threads.
How do you fix thread tension?
If the tension isn’t perfect, fix it by adjusting the bobbin spring; tighter if the bobbin thread shows on the upper layer, and looser if the needle thread shows on the underlayer. Make another test seam, and examine the stitches, repeating until the stitch is balanced.
What tension should I use for polyester?
Fortunately, you don’t need to think too much about it – set up your machine for polyester, and it will cope with most types of poly fabrics without further adjustments being needed. As a general rule of thumb, the upper tension will usually be around a 4.
Why can’t I sew a straight line?
Since the needle is constantly moving, you will not sew straight if you watch it as you stitch. The seam guide does not move so it’s much better to focus there as your fabric moves along, resulting in much straighter seams.
How do I know if my bobbin tension is correct?
The thread should unwind just slightly and the bobbin case should drop an inch or two. If the thread unwinds without resistance and the case slips to the floor, your bobbin tension is too loose. If the bobbin case doesn’t budge, your bobbin tension is too tight.
What width should my sewing machine be on?
A straight stitch has no width so it makes sense to set the dial at “0”. However, each machine varies so you will want to set the Stitch Width dial at the position where the needle is centered over the stitch plate. This will give you the most accurate seam allowance.
