Diagonal Strip Quilt

There are a few different ways to make these Diagonal Strip Quilt … but this will definitely be your favorite method, this pipe method below. These are pretty easy blocks to make, but I don’t recommend this quilt to a brand-new comforter, as there are many bias edges (elastic) to deal with. Read the tutorial before cutting all your strips to find out what you need!

It will make a “tube”, which produces 6 blocks. At the end of this tutorial, you will find a chart with sizes and the number of strips needed for each one. Use a 1/4 ″ seam allowance for the steps below. Good luck, rock and don’t give up because you are capable!!

  1. Start with 6 strips 2 1/2 ″ x the width of the fabric (the gelatin roll strips work great on this quilt!).

2. Sew the strips into two sets of 3 strips each. Press the seams OPEN!


3. Place the sets of strips on the right side together, matching the outer edges. Sew the sets of strips together on the two edges (top and bottom in the photo below), creating a closed tube.


Below, you can see the stitches at the top and bottom (next time, I won’t be using such a lightweight bottom fabric … sorry!).


4. You will now need a large square ruler with a 45 degree line. I’m using my 9 1/2 “square ruler from this package, but any large square ruler will work as long as it has a 45 degree line from corner to corner and is larger than your pipe.


5. Quick note: right-handed, so if you are left-handed, start cutting at the left edge of the set of strips, instead of the right, as I do below. 🙂

Align the 45 degree line on your ruler on the bottom line of the points. Make sure it is aligned with the dots along the entire length of the ruler.


Cut along the right edge of the ruler, as shown.


6. Move the ruler to the top line of the points, again aligning the 45 degree mark with the line of points and the corner of the cut edge, as shown.


Cut along the edge of the ruler to make your first block.

7. Move the ruler back to the bottom line of the points, align everything, making sure that the corner of the ruler is on the cut edge and make another cut.


8. Continue aligning the ruler at the bottom and top and making cuts until you cut the entire strip tube.

Each strip tube produces 6 triangles (blocks).


9. Carefully open the triangles and press the center seams to the side or open. The edges are cut into the slant grain and are very very elastic … so handle them carefully and do not pull or push with the iron. This tip is fabulous for getting those extra-flat blocks without stretching them.

Each block measures 8 1/4 “square. In fact, mine was just under 8 1/4″… but close enough.


10. Repeat the steps above to create all your blocks and layout as desired. To sew the blocks, place them on the right side and attach where the seams meet (or just keep the fabric in place like me) and sew. Again, be kind to the biased edges!


The stitches meet without much noise if you cut them correctly.


Once sewn into the quilt, you can hardly say that some seams do not match perfectly! Don’t worry too much.

After you are done making this quilt top I highly recommend stay stitching (normal stitches/stitch length is fine) around the edges to prevent them from stretching during finishing.  I always add stay stitching to every quilt top!

*This is assuming a finished block size of 7 3/4 ″ … they can be slightly smaller than that. I also didn’t include queen and king sizes, because I honestly don’t recommend doing it on anything larger than a twin because of the elastic edges and many matching seams. You will also die of boredom by making all the strip tubes.
