Inset Triangles and On-Point Sashing

On a few of my posts sharing my current on-point scrap quilt, many readers have asked about the final assembly process.  Well, I remembered to take a couple photos as I sewed my quilt top together so I can now share the process I use.


The first step is to get the layout how you want it.
I find a design wall really helps with the next steps.  It can make assembly so much easier if you can see what is going on.



Here is how I add sashing.  For my 8" blocks, I decided to go with a 1" finished sashing.

The first step is to sew a strip between all the blocks and create diagonal "rows".
Next you need to cut the sashing to run parallel to the rows.  If you look in the upper left, you can see the strips exploded out.  You can just simply measure them with a tape or I just do the math.  

In the lower right, you can see I have begun to sew on the sashing to the blocks.  You do this before you sew on the inset triangles to the edge.

I usually make square quilts when I use this layout because rectangular quilts cause some difficulty.  Those with an eagle eye can see that the 4th strip down will require a partial seam (yuck).  Because the seam is long, it is not that hard.  The process is just awkward.



The next step is to cut and sew your inset triangles to the rows.  I can never remember the formula for cutting the right size triangles, so I turn to my phone.  I swear by the Robert Kaufman quilting calculator app.  Just choose the set-in triangle option and put in the finished block size plus the finished sashing size. In my case it is 9" (8" block plus 1" sashing).

In my case, I start with a 14" square and cut diagonally twice.  Are you wondering how much fabric that requires?  Turn to the app again.  This time use the Pieces to Yardage option.  I find this choice on the calculator so useful!

For this quilt, I have decided to add in my triangle detail.  I have previously shared the tutorial here.
If you struggle aligning the sashing when you sew your rows together, I share a tip here - it works perfectly!

This layout really is pretty easy if you just remember the order to sew the pieces together.  

Looks like I am on my way to having another finished quilt top soon.  Guess I had better start looking for some backing fabric!

I always have to think about the measurements so much that I end up making squares sew everything on and then sew around the quilt to hold all the bias together and then square it up cutting all those parts of the squares off that I don't need - it is a not a waste as I do save all the triangles that I cut of and it makes it less stressful to me.
I like how you do yours, and I love what the sashing added.

Agreed, that Kaufmann app is the best. I use it all the time.
I love the scrappy look to your setting triangles. The details you add in make for a beautiful finish. This one is no exception. Thanks for showing us your process.

I always forget I have that app - guess I need to look at it again. Thanks for the reminder! This quilt is turning out to be a charmer!

I am sooooo glad you posted this. I am working on a low volume 4 patch set on point and had worked out in my mind how I was going to join the blocks. Luckily I was on the right track. Now I can use your tutorial if I run into any difficulty. Was kicking around whether I should go with 2" sashing but now I am going to opt for 1".

Thank you for writing this all up, Cynthia. I got stuck doing a partial seam, too, and wondered if I had somehow missed some key step. Glad to see it all laid out in order like this.

And wow, that dark sashing (is it chocolate brown?) and the inset pieces on the setting triangles really make these blocks sing!

This is such a great border. Thanks for the links too.

The sashing and border is giving it that special "pop". Beautiful.
