This is my finished tablerunner which started life as a Dresden Plate UFO cut from Liberty Lawn fabrics about 8 years ago. I have used the Easy Scallop tool by Darlene Zimmerman (made by EZ Quilting) to create the scalloped border. This is the second time I've used the tool, and I like the vintage look which it gives to the item.
Step one: trim the border to a consistent width - I have trimmed the flower fabric to 3.5 inches wide. Measure the length of the borders and decide how many scallops you want. My side length was 32.25 inches, and I decided on 5 scallops. Rounding up gives a scallop of 6.5 inches. My end borders are 13.5 inches, so I think I will get away with the 6.5 inch scallop on the ends as well.
Step four) Trim the border to the edge of your binding, ensuring that your inner points have a scant 1/4 inch seam allowance (no need to clip). I like to lightly steam press the binding outward from the quilt, I find this helps it to turn over the edge more easily. Turn the binding to the back, and hand-stitch it down. Finally, I give another light steam press to encourage the edge to lie flat. You are finished.!
