Technique #2: 2 squares = 2 Nine Patches
This is a sweet little technique for making nine patch quilt blocks two at a time—a positive (dark squares in the corners) and a negative (light squares in the corners)—from two squares of fabric.
The perfect place to use this is a quilt made of nothing but nine patches, set edge to edge, with no sashing.
For a 4-1/2" finished Nine Patch the calculation is:
4-1/2" + 1-1/2" = 6"
Cut one 6" square from each of two contrasting fabrics.
To calculate the 'cutting number' divide 6" by 3 which equal 2".
With RST, align all the edges and stitch a 1/4" seam on two opposite sides. Use pins to hold the square together if needed. You'll want to keep all the edges even.
Give the unit a quick press to keep things neat.
Now we'll need the 'cutting number' that we calculated as 2" back in Step 1.
At the rotary cutting mat, align the 2" line of the ruler with one of the stitched edges. Cut. Align the 2" line of the ruler with the freshly cut edge and make another cut.
Press the pieced strips, first closed to set the seam and then towards the darker fabric.
You now have two 2-strip units that measure 3-1/2" x 6" and two single strips, one of each fabric, that each measure 2" x 6".
Layout these pieces in a light-dark-light and a dark-light-dark order.
With RST, stitch the single dark strip to the light strip in one of the sewn units.
With RST, stitch the single light strip to the dark strip of the remaining 2-strip unit.
Press as before with seams towards the dark.
Your strips sets look like this. Both should measure 5" x 6" at this point. (Remember our finished block size is 4-1/2"—which is 5" unfinished.
With right sides together and matching seam allowances, stitch the two short sides together. (The seams will nest to help with the alignment.)
Cut in from both sewn edges by the cutting number (2") and you have this. This is the second cut in the photo below.
Now layout the patchwork pieces in positive (dark in the corners and center) and a negative (light in the corners and center) nine patch quilt blocks like this.
With RST, sew the corresponding strips set together. Pin if needed to match seam allowances.
After stitching, press flat to set the seam and then open towards the darker fabric in the outside patches.
That's all there is to it to making two Nine Patch quilt blocks from just two squares of fabric.
