If the upper thread appears as a single line, the lower thread is incorrectly threaded. Instead of the appropriate tension being applied to the lower thread, it is pulled through the fabric when the upper thread is pulled up.
Can you use zigzag stitch for stretchy fabric?
Because of the structure of the stitches, zigzag allows the seam to stretch. Zigzag is a classic for sewing stretch fabrics on a home machine, and if that’s the only stretch stitch your machine offers, it’s a great option, but it is not necessarily the best option.
What stitch is simplest and frequent used?
The running stitch is the most basic and most commonly used stitch, in which the needle and thread simply pass over and under two pieces of fabric. It’s exactly the same as a basting stitch, except it is sewn more tightly to create a secure and permanent bind.
What setting do you set a sewing machine for zigzag stitch?
Set the machine for zigzag stitch. For machines with adjustable stitch length and stitch width, use with a width setting of at least 5.0mm and a length setting of approximately 2.0mm. Use an Open Toe Foot (additional accessory for some machine models) so that the area in front of the needle is unobstructed.
Why is my zig zag stitch pulling the fabric together?
This is actually not an uncommon issue with machines and zig zag stitches and it doesn’t always have to do with thread tension. I usually see this issue myself when sewing with lightweight knit. It usually means the fabric doesn’t have enough stability so the stitches start to pull the fabric towards itself.
Why is my fabric scrunching when I sew?
Cause. Tension pucker is caused while sewing with too much tension, thereby causing a stretch in the thread. After sewing, the thread relaxes. As it attempts to recover its original length, it gathers up the seam, causing the pucker, which cannot be immediately seen; and may be noticeable at a later stage.
Why is my stitching wonky?
A blunt or damaged needle is the number one culprit for poor stitch quality and can lead to any number of stitch problems, including skipped and uneven stitches and thread shredding.
Why does my zigzag stitch look weird?
The zig zag stitch is a strong stitch, but if the tension is too tight the stitch will pucker and snap. Always check your sewing machine tension before trying the stitch on new fabrics.
