How does a zigzag stitch work?
When creating a zigzag stitch, the side to side motion of the sewing machine’s needle is controlled by a cam. As the cam rotates, a fingerlike follower, connected to the needle bar, rides along the cam and tracks its indentations. As the follower moves in and out, the needle bar is moved from side to side.
What stitches are used for what?
Sutures, commonly called stitches, are sterile surgical threads that are used to repair cuts (lacerations). They also are used to close incisions from surgery. Some wounds (from trauma or from surgery) are closed with metal staples instead of sutures.
What tension should I use for zig-zag stitch?
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. If you are doing a zig-zag stitch, or another stitch that has width, then you may find that the bobbin thread is pulled through to the top.
Can you use a zig zag stitch with a walking foot?
Yes, you can use your walking foot for more than straight stitching. A zig-zag stitch should be just fine because all the movement in the stitch pattern is forward. In fact many of the decorative stitches on your sewing machine are just fine to use with your even feed foot installed.
When did zigzag stitch begin?
Blanchard is best known as the inventor of the zig-zag stitch sewing machine, which she patented in 1873. The zig-zag stitch seals the edges of a seam, making a garment sturdier.
Do stitches leave scars?
Traditional stitches that look like knots sewing the wound together can leave little white dots of scar tissue, especially if left in too long, so make sure your doctor has given you clear instructions on when they need to be removed.
Why is my zig zag stitch puckering the fabric?
The stitches in your fabric will pucker if there is too much tension in the seam thread. It is a dead give-away that the crafter did not sew the seams properly. A zig-zag stitch is a side to side stitch used for decorative sewing, stretch fabrics, and seam finishing.
Why does my sewing machine keep jamming underneath?
However certain you are that the problem with the machine is most likely due to a huge tangled mess of thread in the bobbin underneath the fabric, the most common reason for the jamming is usually the lack of sufficient tension in the upper thread.
