The SPIKY Side
The stitch width knob is usually located on the front of a sewing machine to determine the side-to-side motion of the needle as it stitches.
A foot that allows the needle to sew from side to side is a zigzag foot. The foot has an open middle so that the needle can move freely from side to side.
"Purl wise" refers to the method of inserting the needle into a stitch for purling in knitting. When you work purl stitches, you insert the needle from back to front through the stitch on the left needle. This technique creates a "purl" stitch, which is characterized by its bumpy texture on the fabric's front side. Understanding this method is essential for creating various knit patterns and textures.
The machine that has a needle that goes from side to side is an overlock serger. It is used to prevent fabric from fraying.
One front is an increase stitch done this way: Pick up the horizontal strand with the left needle from front to back between the last stitch worked on the right needle and the next stitch to be worked on the left needle. Then, insert the right needle into the back of the loop, and knit it.
The needle clamp is collar and screw device that holds the needle to the needle bar. The needle bar is the part that goes up and down as the machine sews and is in front of the pressed foot bar.
Do you mean "slip the first stitch purl wise"? If so, that means slip the stitch to the right needle by inserting the needle through the front loop from top to bottom, then the yarn to the back and continue knitting.
To find north you will need the magnet, a needle, a piece of very thin paper & a bucket of water. First you need to take the positive side of the magnet and slide it across the first half of the needle, as if you were striking a match, fifty times. Then do the same with the negative side of the magnet and the other side of the needle. Afterwards, put the needle in the paper so that there are 2 holes and the needle lies horizontally, then place in the water. The positive side of the needle will point North.
Assuming that in the previous row you have wrapped stitches it is now time to pull those wraps up onto the needle and knit them together with stitches to prevent holes from forming in the knit fabric. Knit up to the next wrapped stitch but do not knit the wrapped stitch yet. When viewing the knitting from the public (front or knit) side, insert the tip of the right needle into the wrap on the front side of the work and pull it up, over the stitch it is wrapped around, over the tip of the left needle and to the BACK of the work. The wrap is on on the needle, behind the original stitch. Knit the wrap together with it's stitch as if you were knitting two together through the back loops. When viewing the knitting from the private (back or purl) side, insert the tip of the right needle into the wrap on the BACK side of the work. You will have to peek over the top of your needles to see where to catch the wrap. Pull it up, over the stitch it is wrapped around, over the tip of the left needle and to the BACK of the work. The wrap is on on the needle, in front of but to the left of the original stitch. Purl the wrap together with it's stitch as if you were purling two together.
zigzag machine
yes no to get to the other side
it really doesn't matter, as long as you get it threaded!
