For Bonnie Hunter’s Easy Street Mystery Part 3, we are asked to make more (I’m still working on these units from Orca Bay ) shaded four patches. While the method Bonnie uses works fine, I’m bored with sewing triangles on squares. So, I searched around on the web and found this method in Billie Lauder’s YouTube video and a couple of other places. Although, the instructions weren’t for the size we need. So I decided to experiment and I came up with this, which works perfectly for me.
1. Cut two 2” purple squares from the purple 2” strips as in Bonnie’s instructions.
2. Cut two 2 3/4” rectangles from the white/black 2” strips.
3. Sew each purple square to a white/black rectangle. Press the seams toward the right. Mine are finger pressed at this point.
4. Sew the two rectangles together with the purple squares at opposite ends, just like a four patch.
5. Clip the seam allowance in the center so you can press the seams toward the white/black on both sides. Again, mine are just finger pressed.
6. Using the Easy Angle ruler or in my case, the Fons and Porter equivalent ruler, slice the finished unit in half diagonally as shown to get two perfect 3 1/2” triangles.
7. Sew two 3 1/2” triangles to the newly cut units as in Bonnie’s instructions to complete two 3 1/2” square unfinished units.
And there you have it. Another way to make the shaded four patch unit.
Update 12/10/2012: It was mentioned to me that this method was also shown in a book by Sally Schneider (Scrap Mania: More Quick Pieced Quilts). So, I’m happy to give credit where credit is due. Although I have no direct knowledge of Sally’s method or the book myself.
Update 6/24/2014: Adding the additional step I’m using to complete the 3.5″ unit. Cut a 3.5″ x 4.25″ rectangle of the corner triangle color. Using the HST ruler of your choice and mentioned in step 6, draw the cut line on the Step 4 unit. Place the solid rectangle on top of step 4, right sides together. Sew 1/4″ on either side of the cut line. Then cut on the cut line. You should have two perfect 3.5″ shaded triangle units.
