It is extremely important to find one with a simple repeating pattern and no border, crocheted works best for this project.
Also, be careful about color and return policies. I ordered one that was cream and planned to bleach it. However, when I tried it, only parts of the runner turned white. It was made with two different types of thread, apparently. In the end, out of desperation, I actually painted the cream to white using cheap acrylic paint from Walmart!! Oh my gosh, it actually worked!
Hot Glue Gun
Measure out how much of the table runner you will need.
Carefully clip between the patterns on the table runner and don’t cut straight into any of the more complicated patterns.
I saved the extra pieces as “snowflakes” for Christmas wrapping embellishments.
Now hot glue the cut table runner to the bottom edge of your panels.
I hand stitched mine in place, but in hind sight, that was a lot of unnecessary work.
Let the lace hang down an inch or so off the bottom of the panel for a pretty touch.
