These are the rulers. They come with wonderful instructions about how to achieve your desired finished unit.
The first thing you do is cut the required pieces: this will include the center of the square-in-a-square block, which is cut as a square, and then the corners which are cut as triangles (for me they are of my background fabric.)
You take the center square and align it with the appropriate size square on the Companion ruler.
Then you trim the corners off. Easy!
Sew one of the corner triangles to one diagonal edge.
Here the seam is stitched, but I used light thread so it is hard to see. Sorry!
Press by setting the seam and then opening the triangle. It is intuitive to press it that way just like when making a flying geese unit. However, when I began piecing everything together for the sashing, I realized that the directions said to press some of them (the middle units--my red ones) toward the square, not the triangle. Oops!
Next add another triangle to the other side.
When it is pressed, you end up with a wonky unit like this. Never fear!
Using the Fit to be Quarter ruler in the set, you line it up at the bottom right corner with the original size of the square that you cut. You can see that one of the diagonal lines will match the right side's diagonal seam.
When it is all aligned, you trim off the side and top with your rotary cutter.
The turn it around to the third edge and trim that, too,
You end up with a nice, square unit again.
Turn it upside down and repeat the process...
...by removing the other two corners
Then sew on the other triangles in the same manner as before
It is easy chain sewing
Press the third corner
Add the fourth
now you have another half true, half wonky block.
Just use the ruler and trim the three sides and
A perfect square-in-a-square block!
It takes quite a few steps, and lots of trimming, but the perfect block is so worth it! I've made these the traditional way and no matter how careful I am, they come out a bit wonky or skewed.
I finished all of these and added the top and bottom strips and went on to sewing them together into the sashing strips. However, the points needed to match so I had to pin! I try to avoid pinning at all costs, but it is necessary here for good matches.
It occurred to me that not everyone may know the technique (which is pretty common--it isn't my idea at all, I can't remember when I learned it) that I use to match points. I think it is referred to as "the three pin technique" (or at least it is in my head, ha ha!)
Start by using one pin to match the point. Push the pin from the back of one unit, right at the intersection of the seams of the point
Then continue pushing the pin through the point on the right side of the second unit
Ram both pieces tight together and up to the head of the pin. You want it all tight together so it doesn't shift!
Next you put a second pin as close to one side of the first point as possible, and then use a third pin on the other side.
Remove the first pin.
Sew the pieces together. I leave the pins in and go slow so I don't hit one. (sssh, don't tell the sewing machine police that I sew over pins!) You don't have to, but I want to keep it all from shifting even a tiny bit, and sometimes when you remove a pin, things move.
Or, after you "three pin" several, you can remember that you have those nifty "fork pins" and you can use them instead. With the matching, first pin in place, straddle it with the fork pin!
I had to press this seam open because there was so much bulk where those points met, so that slowed me down a bit, too.
This is a complete pieced sashing! I have several done but need to finish the rest today.
Do you want to see a sneak peek of how all of this is going to come together? I sure did!!!
I can't wait for the rest of the patterns! This is going to be a great quilt!
Have a great day!
