Ordinarily, stitches are knitted in the same order in every row, and the wales of the fabric run parallel and vertically along the fabric. Here's how I care for the things I have been knitting.
For example, differently colored leaves and petals of a flower could be knit separately and applied to form the final picture. Fabrics in which the number of knit and purl stitches are not the same, such as stockinette, have a tendency to curl; by contrast, those in which knit and purl stitches are arranged symmetrically (such as ribbing, garter stitch or seed stitch) tend to lie flat and drape well. This will tell you the group of skeins that are from different dye lots, though they are dyed together and this will give different strips while knitting.
A third but less common method, called combination knitting, may also be used. When a person is ready, they will be able to learn more complex stitches. There are also different types of knitting needles like Addi knitting needles, Clover knitting needles, Misc knitting needles, Crystal Palace, Rosewood and HiyaHiya
It will just some time at the beginning, but you will learn and get experience. It doesn't all happen at once.
