How To Sew Quilt Blocks Together With Sashing

Back when your interest grew in quilting, those unexplained quilting phrases and terms might have surprised or confused you. Now that you understand quilting basics, it’s time that we explain to you another intriguing method to sew quilt blocks together.

On this note, here’s your tutorial guide to understanding how to line up sashing on your quilt blocks.

When an amateur quilter created the world’s first quilting design, he never got help from the fancy sewing machine, tools, or DIY tutorials. If quilting was a mere process of assembling torn-out clothes together, what makes it so expensive today?

Although materials and equipment are exceptional, there’s no wonder that you can build an extraordinary design even if you run out of creative ideas or versatile fabrics.

How To Sew Quilt Blocks Together With Sashing?

The answer to this comes in one effortless motion: here’s presenting everything making quilt sashing ever more popular than what it is now.

There are two major methods to sew quilt blocks. You can either put strips between blocks in rows or add stripes to both sides of blocks.

2 Quick Methods of Quilt Sashing

Quick Methods of Quilt Sashing

Before delving into the steps, it’s imperative to understand the term first. Sashing refers to the strips of fabrics that get sewn together between rows and columns.

If you’re new to this concept, then let’s remind you that quilt sashing serves to enable quilt blocks to stand out without even appearing too crowded. It also helps unify the quilt when just one sashing fabric gets used.

As it’s a standalone design, saying that it serves as an elementary design element in the quilt is nowhere an exaggeration. The size can get extended if the quilt gets made out of sashing. That’s all you need to understand about the process before diving into the steps below.

Method 1: Putting Strips between the blocks appearing in rows

Step 1: Using Long Strips between Blocks

Long Strips between Blocks

Use long strips to put them between blocks in the rows. As it comprises multiple long strips that can get distorted, it can complicate the overall process. So, to ensure simplicity, you need to pin them well.

Step 2: Pin the Borders

As you include borders to your quilts, pin them eventually. Measure the differences carefully; it should stay uniformed! If you find sewing long strips to be more seamless, you need to cut the strips for blocks in the row (keep measurements constant).

All strips must be exactly of identical size. After completing rows, measure them and cut joining strips. Again, please consider that they are in equal sizes.

One Quick Example:

Let’s say rows have 12-1/2-inch blocks prior to sewing, while the strips have 2-1/2-inches. The length should be 44-1/2 inches.

Blocks after getting sewn measure 12 inches (each). So, 12 inches each multiplied with 3, i.e., 36 plus 4 (i.e., two 2-inch as sewn in the strips) plus 4-1/2 (i.e., two strips 2-1/2-inches on edges, as sewn on one side, making each 2-1/4 each). You can calculate the required size by taking blocks plus all strips (finished sizes). After this, add 1/2-inch for the allowances of seams on every end.

Step 3: Sew The Borders Carefully

After you complete measuring the sizes, it’s time to sew the borders. Either use your fancy sewing machine or enjoy solving those quilt puzzles through hand quilting.

Method 2: By Adding Stripes to Both Sides of Blocks

Adding Stripes to Both Sides of Blocks

If you think the aforementioned method is really complex, here’s your simplest one! Read on.

Step 1: Add strips to the two sides

After adding the strips to two sides of the blocks, put them together. This way, you’ll have no problem when adding cornerstones. One great perk of this method is that you get to cut the strips to the required measurement. So, it helps corral fullness in blocks. In addition, it also ensures flatness in the top layer.

Step 2: Lay It Out

After you lay it out, you’ll see that the blocks get sashed on their upper side and right side. There’ll be only long strips required, and it’ll get placed on the bottom (down the left side).

Step 3: Sew Rows

After you complete the sewing method, you’ll see the smashing gets done almost. The only thing is to follow the plan to add the exact size strip to its bottom. Cut it properly for that right corner before sewing it.

Step 4: Adding Dimension to Sashing with Cornerstones

Now, it’s time to include another dimension to sashing with the cornerstones. Start off with cutting strips in the same dimension as blocks. Cut two strips for a single block and one for the row. Put the cornerstones on an exact number of strips as that of the blocks.

Step 5: Start with Sewing

To begin with, sew the very strip on the block’s right side. Press sewn strips towards the strip. Do the same with the cornerstone toward the strip to allow nesting of the seam. After doing so, it’s time to assemble the blocks into rows.

Step 6: Making Cornerstone Strips

When you intend to make cornerstone stripes, ensure that you do it for the left edge of rows. It will remain onto the individual rows. With that being said, the only long strip is across its bottom.

Step 7: Start with the Bottom

Put the left corner strip. Add the chosen bottom strip. For ease, do it with one row, rather than waiting until the whole top gets constructed. Instead, you could even add it to every block before you put the blocks together. Press seams in the opposite directions to make joining rows more accurate. After rows get put together, pin all sashing seams carefully.

Some Lesser-Known Facts about Sizes and Measurements

Some Lesser-Known Facts about Sizes and Measurements

When you choose the same background fabric, add the cornerstones. However, selecting contrasting colors on blocks and cornerstones make colors pop out. Let’s say a quilt with yellow cornerstones can echo the squares in star blocks.

If you’re wondering about the width of the sashing strips, it’s really up to you. As a quick fix, you can use a way to cut sashing as that of the width in the block patches.

Make it half or twice the width. Let’s say, if the nine patch block comprises 4-inch squares, then cut the sashing strips around 4-1/2-inches. This will allow 1/4-inch allowance of seams, 2-1/2 inches, or even 8-1/2 inches.

Alternatively, you can go for 1/3 of the block width. In this way, even if you have around a 9-patch block plus 4-inch squares finishing at 12 inches, you can choose 3-inch finished sashing.

For modern design lovers, a Fibonacci sequence can be extremely eye-catching. Sashing does not have to be all about the even width over quilt tops. You may implement an asymmetrical quilt design with different widths with sashing.

Quilt sashing has become a popular method to create standalone designs for different purposes. Did you know that quilt sashing designs have paramount importance in the fashion industry? Indeed, its significance has revolutionized the fashionista’s style statements.
