Knitting a triangle may seem difficult at first, but after breaking it down to two techniques anyone can do it. There are two ways to create a triangle. You can start from the base and decrease until you get to the tip or you you can start from the tip and increase stitches to get to the base. There are several different ways to increase or decrease stitches.


Things You'll Need

  • Yarn -- any weight

  • Knitting needles-- any gauge

  • Stitch markers

  • Scissors

Starting From The Base

  1. Cast on enough stitches to form the base of your triangle - the more stitches you cast on, the larger the triangle will be
  2. Knit the first row
  3. Knit the first stitch, knit two stitches together (k2tog)
  4. Knit until the last 3 stitches, knit two stitches together (k2tog), knit last stitch
  5. Repeat steps 3 and 4 until there are 4 stitches left
  6. Knit two together (k2tog), twice
  7. Knit two together (k2tog)
  8. Knot the last stitch

Remember that if you are decreasing a stitch in the beginning of your row, that you decrease the same amount at the end of your row. Otherwise your work will not be even.

Starting From The Tip

  1. Cast on 4 stitches
  2. Knit the first stitch
  3. Yarnover (YO) by bringing your yarn from the back of your work to the front
  4. Knit two stitches
  5. Yarnover (YO)
  6. Knit the last stitch
  7. Repeat steps 2-6 until your triangle has reached the size you want it to be
  8. Bind off all stitches



Remember that if you add one stitch by in the beginning of your work, you need to do the same at the end of your work otherwise your work will not be even.


You can place your stitch markers to remind you where you need to yarnover or increase your row.

Other Techniques

Once you have had more practice and really understand your basic stitches, you can learn new increasing techniques. Make one (M1) and knit forward and back (kf&b) are two ways to increase your stitches, and these techniques leave a hole in your work, as a yarnover will.


Other decreasing techniques include slip-slip-knit (ssk) and slip-knit-pass (skp), which will angle your stitches differently than k2tog will, and create a more seamless piece. Learning these techniques will allow you to be able to create triangular knitting pieces, as well as customize any other project you have.



Customize your triangle project using the above techniques. For a shallower triangle, knit more rows between increase or decrease rows, or for a sharper triangle, consider increasing every row instead of every other.
