How to Close a Ripped Seam
Start with a single-threaded needle. Turn the garment inside out. Trim any loose threads, align the seam, and pin in place. Starting 1 inch before the tear (working from right to left), use the backstitch.
(A) Pull the needle up through both pieces of fabric.
(B) Make a stitch at 1/16 inch to the right.
(C) Bring the needle about 1/8 inch to the left (bypassing point A) and pull the needle up and through.
(D) Reinsert the needle at 1/16 inch back to the right so that it pokes through next to the point where the needle entered at point A. Continue along the seam with this back-and-forth motion. Finish 1 inch beyond the tear.
