This tutorial is to show you how to make the sashiko projects into table mats with mitered corners.
1. After pressing your sashiko stitched piece, lay it over a piece of quilt batting and trim the batting to fit the top.
2. Next lay the batting and sashiko stitched piece (sandwiched together) over the backing fabric and adjust until there is at least 1 1/2″ of backing showing all around.
Just to make sure, the sandwiched fabric stack is like this: the backing (wrong side of fabric facing up), the filling layer, the sashiko stitched piece on top, facing upward) Cut the backing to be exactly 1 1/2″ wider than the filling and top all around.
3. Fold the edges of the backing in 3/8″ and press.
Next fold the two long sides over the front of the mat and press again. The should end up just about touching the sashiko stitched line. If not adjust until they do. If this seems unclear to you, take a look at the finished table mat picture one at the beginning of this tutorial.
4. Fold and press the short ends as you did with the long ends. Now, unfold them, and at each end fold the corner into a triangle shape. Press. You may want to trim out some of the folded fabric.
5. Fold the short ends over the front of the mat again, matching the place where the self bindings meet.
