Vertical parallelograms are shapes where opposing sides are equal, and the height is greater than the width. When creating a knit project, vertical parallelograms make a lovely accent for borders and straps. You can also use many of these parallelograms sewn together to make up the body of whatever piece you are creating.
A "skinny scarf" is a great project for learning to knit vertical parallelograms. Since this will be a learning project, you should choose a yarn and needles with which you feel comfortable working.
In order to knit a scarf made up of vertical parallelograms, you will first need to cast on enough stitches to make your first row about 3 inches wide. In order to knit the parallelogram, first knit a "bar increase", or knit a stitch and leave the original stitch on the needle, then knit again into the back loop of the first stitch. Knit to the third stitch from the end of the row and then knit 2 together (K2tog). Turn the work and make a bar increase again, then once again continue knitting to the third stitch from the end and K2tog. Repeat this pattern until your piece is about 4 inches long.
To begin the second vertical parallelogram, bind off the first 3 stitches on the next row. Then make a "Slip Knit Pass" (SKP) or slip one stitch onto the right needle, knit the next stitch and pass the slipped stitch over the knit stitch and continue knitting until the next to the last stitch. Knit a bar increase and turn the work. Continue in this manner until this second vertical parallelogram has reached about 4 inches.
Now it is time to take stock of how you have progressed on your vertical parallelograms and whether or not you like the emerging pattern. Is the slant a bit more pronounced than you would like? Only do the increases and decreasing on every other row to make more rectangular parallelograms. Does each parallelogram not lean enough? Do double increases and decreases. Are the vertical parallelograms too offset or not offset enough? Increase or decrease the number of bind off stitches when starting the next shape. You can also decide whether you want to make the scarf even skinnier or less skinny.
If you like the work as it is, bind off 3, stitch, and knit the next vertical parallelogram, just as you did the first. Continue alternating until you've knit about 12 parallelograms. Bind off, and you're done!
