Iron your batting (if it was a wadded up remnant like mine) on a low heat setting. Be careful not to stretch it out of shape. Then iron your backing fabric on a high-heat cotton setting to get all wrinkles out. You will be sewing your top strips through all the layers of of batting and backing so you want to start as smooth as possible. If you are using a Warm & Natural type batting it has a little bit of adhesive stuff on it (which is why you don’t want to iron directly on it on a hot setting.) This is helpful for keeping your batting and backing fabric together and smooth.
After both pieces are pressed individually, center the batting on the wrong side of the backing fabric. Carefully flip both over and press the backing fabric with batting underneath on a high heat setting. This will create enough of a bond to hold them together without having to pin the heck out of them. If you feel more comfortable, or if you batting isn’t lightly adhering to the backing fabric, you could use a quilters spray adhesive to hold them together.
(Do it carefully on the first few strips so you don’t melt your batting.)
Return to your two piles of strips and this time take the top one from the left-side pile. Pin the strip in place matching the left edges. Repeat the process, sewing another 1/4″ seam and pressing the seam open. Let me stress here, don’t skip the pressing step. Your strips will lie neater and flatter will get a much cleaner looking project in the end.
Repeat these steps, alternating right-side and left-side piles until you have finished sewing all the strips to the edges of the table runner.
See how pretty it looks? Really, you could just stop here and bind if you like, but personally I love the look of quilting, so let’s do that next!
And voila! Here’s what it looks like fresh out of the dryer. I love how a quick wash softens up the look of the whole thing.
