Adding sashing between quilt blocks and block rows can dramatically change the look of a quilt top. When separation and definition between blocks is your goal, sashing is a traditional, useful technique to have in your bag of tricks.
There are a few tips for aligning sashing strips that will make this process easier and also lead to much nicer results when adding sashing. After all, off-kilter sashing distracts the viewer’s eye and can even cause a slight sense of vertigo, and no one wants that! Here’s a foolproof technique for making sashing strips line up perfectly:
Follow your quilt pattern’s instructions for sewing blocks (represented by the blue squares) and short vertical sashing strips into rows. Stitch 1 long horizontal sashing strip to a block row, and trim ends of strip even with the row (if applicable). Press well.
Fold the long sashing strip up onto block row. Pinning only through long sashing strip, insert pins at raw edge to mark seam lines of each short sashing strip.
Open the long sashing strip.
With right sides together, position next block row on long sashing strip, aligning seams with pins. Re-pin through both layers. Sew seam.
Open and press. Look how nicely those vertical sashing strips line up with each other! Just a little pin-marking makes such a big difference, and you’ll never again have the nasty surprise of sashing strips that don’t line up.
