In knitting, an increase is the creation of one or more new stitches, which may be done by various methods that create distinctive effects in the fabric. Most knitting increases either lean towards the left or the right. Methods of single increasing (knitting) Yarn-over increase or "eyelet increase" – The simplest increase is to do a yarn-over between two existing stitches. On subsequent rows, the yarn-over will be knitted, making a new stitch. This disadvantage of this method is that a small hole (eyelet) is produced at the yarn-over. This can be improved by twisting the yarn-over stitch - similar to a "make one" (below) or purling the increase through the back loop in the return row. Raised Increase – Lift the strand connecting two knitted stitches in the row below onto the left needle (effectively producing a yarn-over) and knit it, either normally or twisted. This method (especially if twisted) leaves almost no hole, since forming the yarn-over stitch from the (presumably tight) connecting strand draws the two neighboring stitches together. If the strand is picked up coming from the front, the result will be a right-leaning decrease (M1R). If it is picked up from the back, the result will be a left-leaning decrease (M1L) Bar increase – Knit the stitch normally but without transferring the knitted stitch to the right needle; the same stitch is then knitted through the back loop (KFB - knit front & back). This increase creates a bar or a nub on the fabric. Moss increase – Knit the stitch normally but without transferring the knitted stitch to the right needle; the same stitch is then purled. This increase makes a bar or nub on the fabric. Lifted Increase – For a right-side increase, knit into the right leg of the stitch of the row below the next stitch to be knit, then knit the next stitch. For a left-side increase, knit one stitch, then knit into the left leg of the stitch of the row below it through the back loop. This kind of increase can be visually subtle. "Make One" (M1) – Place a half-hitch loop on the needle between two stitches, either before or after, and twisted either left or right, depending on the desired effect. Column of Increases – A second strand of yarn or roving is passed up the piece. The second strand is used to make an extra
