How to Add Sashing

(Framing Your Blocks for a Polished Finish)

Step-by-Step Instructions:

Sashing strips are the fabric pieces sewn between quilt blocks. They separate busy patterns, frame your hard work, and can easily increase the overall size of your quilt.

Materials Needed:
  1. Completed, squared-up quilt blocks
  2. Sashing strips (cut to size)
  3. Cornerstones (optional squares)
  4. Rotary cutter, mat, and ruler
  5. Pins and sewing machine
Tips for Success:
  • Always measure your finished blocks before cutting sashing to ensure an exact fit.
  • Pin generously at the ends and the center to prevent the long strips from stretching.
  • Press seams toward the sashing strips to reduce bulk, unless the sashing is very light/sheer.
1. Measure and Cut
  • Measure the exact height and width of your finished quilt blocks. Cut your vertical sashing strips to match the height of the blocks. Cut horizontal sashing strips to match the width.
2. Add Vertical Sashing
  • Pin and sew a vertical sashing strip to the right side of your first block. Join the next block to the other side of that sashing strip. Repeat until your row is complete, ending with a block (or adding a final sashing strip on the end if your pattern calls for it).
3. Create Horizontal Sashing Rows
  • If you are using cornerstones (small squares that sit at the sashing intersections), sew a horizontal sashing strip, then a cornerstone, then a sashing strip, alternating until the row matches the width of your block row.
4. Pin the Rows Together
  • Lay a horizontal sashing row right sides together with a block row. Pin carefully at the intersections, ensuring the cornerstones align perfectly with the vertical sashing strips in the block row.
5. Sew and Press
  • Sew the rows together using a consistent 1/4 inch seam allowance. Press the entire quilt top, pushing the seam allowances toward the sashing strips to create a crisp, flat finish.

Top FAQs for Adding Sashing:

What is the difference between sashing and borders? +

Sashing goes on the inside of the quilt top, acting as a grid that separates the individual blocks. Borders go around the outside perimeter of the entire assembled quilt top to frame the whole project.

Should I use cornerstones in my sashing? +

Cornerstones (small fabric squares at the intersections of sashing strips) are highly recommended! Not only do they add a great design element, but they also act as perfect registration marks, making it much easier to line up long rows of blocks accurately.

How wide should my sashing be? +

It is a matter of personal preference, but a good design rule of thumb is to make your sashing width about 1/4 to 1/5 the width of your quilt blocks. For example, a 12-inch block looks well-proportioned with a 2-inch to 3-inch finished sashing.

Why is my sashing wavy? +

Wavy sashing usually occurs if you cut long strips of fabric and just sew them on without pinning, allowing the machine to stretch the fabric as it feeds. Always cut your sashing to the exact mathematical measurement of the blocks and pin the ends and center before sewing.
