Method

  • Before you start sewing your triangles together, it’s important to note that each triangle will have 2 bias edges and a cross-grain edge.
  • You will be able to tell the difference between the two as the bias edges are stretchy. The cross-grain edge is less so.
  • You can see how we have sorted the triangles below and pinned the cross-grain edge for each color stack. This makes it easy to know where the cross grain is as we start to sew.

  • When you are ready to start sewing, lay out your triangles in the pattern shown below – one up, one down, one up, one down and so on.
  • You need to ensure that the cross grain edges are at the top and bottom as shown in the image below.

  • Place one triangle on top of the corresponding triangle (right sides together) and sew along the bias edge with a quarter-inch seam.

  • Once sewn it should look like this.

  • Now place the other triangle over the middle triangle (right sides together).

  • Now sew down the bias edge with a 1/4″ seam.

  • Your triangles should now look like this.

  • You can continue to add more triangles in the same fashion until you have the strip as long as is required for your particular project.
  • You can then create more strips as needed and sew them together as we have done for this table runner. Click the link for the triangle table runner tutorial.
