The best way is to knit the bar between the stitches. This is known as a 'bar increase', and there are how-to's and videos online.
If you pull your knitting apart slightly, you'll see a bar just beneath the point on the needles where you are knitting. Put your right needle under this bar, lift it up and put it on your left needle. Knit it as normal. Ta-da! Now you have one more stitch.
There is no stitch - skip that square when reading the chart. They include the "blank" space on the chart for clarity (lol!), or visual continuity.
Yes, because you are knitting two stitches from the same stitch.
A marked stitch is a stitch where you have placed a knitting marker. A pattern may tell you to place a marker at a certain stitch, and to do some particular thing in a subsequent row when you come to that marked stitch.
Cross stitch is a form of embroidery. (Cross stitch designs are done on grids, so they look like they might be for knitting. You could probably use some cross stitch designs for intarsia or fair isle color knitting.)
There are many kinds of stitches in knitting. There is normal stitch, purl stitch, garter stitch, stockinette stitch, ribbing stitch, seed stitch and lots more. Loads of stitches are actually made up of other stitches merged, chopped and changed.
Yes.
Purling is knitting the purl stitch.
Stocking Stitch (knit a row, purl a row, repeat)
A tomboy stitch is also known by other names: French knitting, i-cord, or tomboy stitch. You can make your own "french knitting" machine, by using Popsicle sticks (as is done in one of the attached links), and I have seen knitting machines to make i-cords, which is another name for tomboy stitch. I have also found another type of cord--a Lucet cord, which is more of a squared cord, rather than a round cord. Attached is a link to a YouTube video for making a Lucet cord.
Assuming you are doing stockinette stitch (knit the front side and purl the back side), your knitting is curling because that's precisely what stockinette stitch does. To make it stop, put a band of garter stitch (knit the front side AND the back side) or ribbing around the piece and that will make it lie flat.
SKPO stands for slip knit pass over. In other words, you slip one stitch, knit one stitch, then pass the slip stitch over the knitted stitch, thus decreasing one stitch in your row of knitting.
The rick rib stitch is a copyrighted stitch from Barbara Walker's Second Treasury of Knitting Patterns, page 260. Because of copyright, it is not legal for me to copy her instructions here. I suggest you visit your local library or knit shop and look it up in that book.
Are you knitting? If by basic stitch, you mean garter stitch, it is because you are knitting on both sides of the work. It may also mean your working yarn is in the wrong place when you attempt to pearl a stitch. A stockinette stitch is achieved by knitting on one side of the work and pearling on the other. When knitting, the working yarn should be at the back of the work, away from you. When pearling, the working yarn should be pulled between the needle and the work,( closest to you) and then work the stitch the same as a knit stitch. This should fix your problem, but if not, please ask more questions.
