When you knit something, the other side is the purl side. If you purl something, the other side is the knit side. Filaments or not.
If you are alternating each stitch (knit, purl, knit, purl) the pattern is called ribbing. If you alternate each row (row 1 knit, row 2 purl) it is called stockinette stitch.
if you are doing stocking stitch you can just reverse it to make a textured pattern so on knit side you would purl the stitch and on purl side you would knit it.
garter stitch is when the rows alternate knit, purl, knit, purl. Since purl is the reverse of knit, for a scarf you just have to set aside a few stitches for your border on either side and knit all of them every row.
stockinette or stocking stitch means knit one row, purl one row. So four rows are knit one row, purl one row, knit one row, purl one row.
To bind off a 2x2 rib stitch pattern, you would knit the knit stitches and purl the purl stitches as you normally would. When binding off, you would knit the knit stitches and purl the purl stitches together to create a neat edge. Continue this pattern across the row until all stitches are bound off.
If it's purl, it's not knit. If you do all purl stitches you get exactly the same fabric as all knit stitches, i.e. garter stitch. This is a rougher looking finish than stocking stitch, but has the advantage of lying flat.
I think you are referring to the phrase "Knit one, Purl two".
Seed stitch is also known as moss stitch. It is when you knit one purl one throughout but in the next row the purl stitches are above the knit stitches in the previous one (like a chequerboard) unlike ribbing where the knit and purl stitches stay in the same column.
it is an abbreviation for Stockinette Stitch also known as Stocking stitch . It is basic stitch where you knit one row and purl one back and repeat just these two rows written as Knit 1 row Purl 1 row Knit 1 row Purl 1 row
"Knit 1, purl 2" is a common stitch pattern in knitting that instructs the knitter to perform one knit stitch followed by two purl stitches in a repeating sequence. This creates a textured fabric, often used in various projects like scarves or blankets. The pattern's rhythm helps establish a unique look, combining the smoothness of knit stitches with the texture of purl stitches.
Stocking Stitch (knit a row, purl a row, repeat)
When you insert the needle into a stitch you can insert it front to back (knit-wise) or back to front (purl-wise).
