First determine what you are using as the pattern center of the area rug. Then measure, in this case 4’7” each way from the center, and mark the carpet. This will give you the 9 feet for the finished rug plus an inch to work with at each end. These machine-made runners are easy to mark across the weft (width); you can run a pencil down the row to easily mark it (Photo 1). The border on this runner was 5 inches (Photo 2).
The way I was taught to sew is to use a thimble on my middle finger and push the needle through the carpet front to back (Photo 7). Some people push the needle from the back to the front. Not to say one is better than the other; this is just the way I was taught.
After you have finished sewing on the end caps, smear some of the latex you used to seal the seams across the finished stitches. This will protect, strengthen and lock the thread in place (Photo 8a).
