Triangle Wheel Quilt Block // Technique Tutorial Tuesdays

This post is part of the Technique Tutorial Tuesdays Series. Click here to see all of the posts and learn more about the series. A few month's back, actually on the 4th of July, I shared with you my triangle blocks that I had made for a quilting 3x6 Bee. Since then I have had a few requests for a block tutorial. So today I will be teaching you how to make a Triangle Wheel Block.

The Tutorial

Triangle Wheel Block Tutorial

This block can be used in many different ways. You can make a 12.5" full block with the triangle or you can use just the 8.5" inner triangles to piece together.

This block is designed and definitely works much better when using double sided solids like Kona Cotton. Kona Cotton does not have a right or wrong side. If you decide to use prints you will need to make sure you cut your triangles the proper direction so the right side will be facing. It will take a bit more planning, fabric and thought when using prints. The inner triangle of this block is Charm Square friendly so this is a great block for all you Kona Swappers.

Material/Cutting List (for 1 Block)

Inner Triangle: Part 1
  • 6 - different color 5" charm squares
Background Border : Part 2

Important Notes

Each inner triangle consists of 6 triangle pieces. Each 5" charm can yield 4 triangle pieces. So to complete one inner triangle you will need two 5" charms. For this tutorial I used 6 different colors for my inner triangle, which gives the block a really fun look. So for this tutorial it calls for 6 different colored charms, this would actually be enough to make 4 identical inner triangles. The reason I wanted to mention this is just so you know you will have extra triangles pieces :) We will be using scant 1/4" seam allowance. I will give pressing directions throughout the tutorial. The overall block measurements have a little fudging room so that you will be able to accurately square up your block to 12.5" when your done.

Lets Begin

PART 1 // Piecing the Triangle

Triangle Wheel Block Tutorial

  • Step 1: Get your charm squares, ruler and rotary cutter/mat
  • Step 2: Cut all 6 charms in half making them 5" x 2.5"
  • Step 3: Take your half charm and measure from the upper left point to bottom right point
  • Step 4: Sub-cut the half charm into two identical triangles
  • Step 5: Cut all your charms squares this way, each charm square will yield 4 triangles
  • Step 6: Lay your triangle pieces out in the order you plan to piece them using the picture here as a guide

  • Step 10: Sew A to B on the second side of your triangle

PART 2 // Adding the Background

  • Step 17: Cut all required background fabrics and prepare inner triangle using Step 1
  • Step 18: Print out your PDF triangle template, take the 2 - 8.5" x 6" pieces and cut the template out of them. You will now have two large triangle pieces
  • Step 19: Lay all your background pieces out around the triangle as a guide for piecing
  • Step 20: Line your first background triangle up with the inner triangle. *Be sure to line up the bottom point of the triangle with the bottom corner of the background fabric, the excess background fabric should be at the top of the triangle* Sew in place.
  • Step 21: Repeat for the second triangle background piece
  • Step 22: Press your seams outward from the center of the triangle

  • Step 23: Square up the top of your block. There should be approx. 1.25" of background fabric above the top point of your triangle after you square up.
  • Step 24: Take your 2 - 10.5" x 3.25" pieces and lay them on the top and bottom of the triangle block
  • Step 25: Sew each border onto the triangle block, one to the top, one to the bottom. Trim up the left and right sides of your block.
  • Step 26: Press your seams outward from the center of your triangle
  • Step 27: You block should now be trimmed up, pressed, and ready for the side borders
  • Step 28: Take your 2 - 13.25" x 2.25" borders and sew one on the left side and one on the right side. Press your seams outward from the center of the triangle.


  • Step 29: With a 12.5" ruler line up the center seam of your triangle block with the 6.25" center mark on the ruler and trim up your block to a perfect 12.5"

    Help! I cant seem to get the center of this block to come out straight and flat. The center edges aren’t coming out straight. I can straighten the, of course, using the 30 degree line but am wondering if I am doing something wrong which is causing this to happen. Any suggestions?
