There are a variety of different knitting looms that can be used in loom knitting. The most common are round, but rectangle looms definitely have their purpose. They are wonderful for making flat panels, and they come in a variety of sizes. To knit on a rectangle loom, you can use the standard loom knitting e-wrap stitch or any number of different stitches designed solely for their use.
Basic Rectangle Loom Knitting
The basic e-wrap stitch can be used for both the round loom or rectangle loom. To knit on a rectangle loom using the e-wrap method, you will need to anchor your yarn by making a slip knot around the anchor peg, or the first peg of the loom. Then, take your working piece of yarn and wrap it around the first peg going from the inside toward the outside of loom. Wrap each peg of the loom. Go down one side of the loom and then across and back up the other side until you are at the peg directly across from the first peg. To make a flat panel you will double back wrapping each peg again. To make a round or oblong piece you will go across to the first peg and wrap each peg a second time. Regardless of the method you choose, once you have two loops on each peg you will anchor your working strand of yarn by wrapping it loosely on your anchor peg. Then, you will take your pick tool and go around the loom starting at peg one and lift the bottom loop over the top. Keep repeating these instructions until your piece reaches the desired size.
Figure Eight or Zigzag Stitch
One of the most popular stitches for the rectangle loom is called the figure eight or zigzag stitch. This works up in a flat panel that comes out of the bottom of the loom. Instead of working down one side and then up the other, you will go back and fourth from one side of the knitting loom to the other. To start, anchor your yarn to the loom using a slip knot. Long loom pegs are set up so that all the pegs on the right side are odd and all the pegs on the left side are even. Take your working yarn and lay it between the first two pegs on the right side of the loom. The yarn should be going from the inside of the loom toward the outside of the loom. From there you will wrap around peg one going around the outside back toward the inside and across so your working yarn is now between pegs two and four. From there, wrap peg two going around the outside back toward the inside and across so your working yarn is between pegs three and five. Continue with this pattern until you get to the other side of the loom and then double back toward the beginning of the loom following the same pattern. Once you get back to peg one you can anchor your working yarn. Use your pick tool to lift the bottom loop over the top loop on each odd numbered peg. Then, do the same with even numbered pegs. Get your working yarn and wrap each peg again using the same instructions. Each time you have two pegs on every peg use your pick tool to remove the bottom over the top. Keep following this pattern until your piece reaches the desired length.
To bind off a rectangle loom, take the loop on peg two and move it to peg one using a croquet hook. Then, use your pick tool to knit off peg one. After that, move the loop from peg one to peg two and take the loop on peg three to peg two. Then, use the pick tool to knit off peg two. Repeat these steps until there is one loop left at the end of loom. Cut the working yarn leaving a 4- to 6-inch tail. The tail will get pulled through the last loop to create a knot. Weave the leftover tail of yarn into the grain with a tapestry needle.
If you want to make something on your long loom using what you have learnt here, there are two items you can make easily. You can make flat panels using either method. Work the panels up to the desired size. Then use your tapestry needle and a matching yarn to sew the panels together to make an afghan. If you have a smaller long loom, you can make a scarf using the figure eight/zigzag stitch. Just work the scarf to the desired length and bind off as usual.
