Triangles - Second Tutorial


First of all, thanks for all the votes in the poll last week to help me pick which quilt top I’m going to make out of the first batch of triangles! There is still plenty of time to vote, as I will be revealing the winner at the end of the Triangles Series. So click here to cast your vote, if you haven’t already!

And now… this week’s main event! Welcome to the second how-to post in our Triangles Series! Today’s demonstration shows you a super slick method to make triangles which was new to me until very recently. Although it is a very easy method, it does require a special ruler, which looks like this:



Alrighty, let’s do this! Step-by-step instructions below:

1. Select Fabric

    Similar to the last method, you’ll need two fabrics to make your triangles. As always, let your creativity take you wherever feels good! You can see my selection in the picture above.

    2. Select Size

      For this method, you start out picking your strip size. I wanted to go smaller than my last demo to show a different look, so I started with 3.5 inch strips. NOTE: this is not the final size of your triangle square!!

      3. Cut Strips

        Once you’ve decided on your width, cut an equal number of strips out of both of your fabrics.  If you don't already have a rotary cutter, here is a great starter kit!

        4. Layer Your Strips

          Now that you have all your strips in both colors, layer one of each color on top of each other, with the fronts facing each other.

          5. Sew on Both Sides of the Strip

            Sew ¼ inch seams along each side of the strips, turning the strips into a tube.

            6. Align Your Ruler

              This is the trickiest step. When I first learned it, it was mind-bending. But once the technique clicked, it was a total life-changer!

              Grab your ruler and your tubes. You’ll want to align one of the lines on the ruler with your thread-line, keeping the tip of the ruler on the tube. Depending on the size of your tubes, the line you use for cutting your triangles will be different. I ended up with 4.5 inch making the most sense, because that’s where I could align the line with my seam and have the tip of the ruler still end up on my tube. If I moved it up a line, the tip would have hung off the fabric, and if I moved it back, I would have wasted a ton of fabric!

              7. Cut Triangles

                Once you’ve got your line picked out, go down the strip cutting triangles. For the first triangle, you’ll have to cut along both sides. After the first triangle, you’ll just align one side of the ruler against the previous edge, as well as aligning your selected ruler-line with your thread-line.

                8. Open the Triangles

                  Depending on how things ended up aligning, the tips of your triangles may actually be sewed shut after cutting! Don’t fret - just yank them apart. You shouldn’t even need a seam-ripper!

                  9. Iron

                    I kid you not - you are now nearly finished. You have a pile of triangles that just need to be ironed! Same as the last method, just make sure you iron all the seams the same direction. If you have a light and a dark fabric, iron toward the dark.

                    10. Trim Edges

                      The last step is to cut off those pesky dangling edges! Grab your fabric scissors or your ruler + rotary cutter, and get trimming!

                      Now you have another stack of triangles, and you’re ready to make another quilt top! What do you think - was this method easier than the first? I kind of think so!

                      Next week I’ll show you some layouts I’m contemplating for this batch, and you can help me pick again. I look forward to seeing what you choose!

                        How do you determine the width of the strips for the size square you need?

                        The only reason I don’t like this method is because all edges are bias. I did try making these with the fabric strips cut on the bias so sides are more on grain. I was much happier with the results.

                        Awesome technique! What size squares did you end up with? Is there a formula to use it you want a specific size?

                        I liked this. thank you. I haven’t seen anyone sew both sides of strips. Very helpful. Thank you.

                        I’ve seen lots of ways to make triangles, but never this one. Thanks for sharing.
