Perfect for ripping out the seamsStitch unpicker without damaging the fabricThread Cutter Clean Cap can protect your hand from puncture and the blade edgeThere are a few different ways to take out a seam with a seam ripper.  Consider the weight and strength of the fabric you are using when deciding which method.  Always make sure to work in good light so as not to nick your fabric.One quick way to remove a long seam of stitching is to use the seam ripper to cut every third stitch on one side of a seam.  Once that is done, you can simply pull out the thread on the other side of the seam.If a seam is not stitched too tightly, you can cut the thread on one side of the seam and pick out an inch or two of stitches. Grasp this inch or so of thread and gently pull to make gathers in the fabric. Just before the thread feels like it's going to break, cut it at the other end of the gathers. You should now be able to pull this thread right out of the seam. (It depends on the weight of your thread and fabric, and the length of your stitches just how much you can pull out at a time.)  Now, you will have a long thread on the other side of the seam and you can repeat the process until the entire seam is removed.Some seams that are tightly stitched will have to be picked out one stitch at a time. Slide the tip of the ripper under each stitch to cut it.  A piece of masking tape can be useful for picking up stray bits of thread.To cut open a buttonhole, pierce the fabric at one end of the inside of your buttonhole with your seam ripper.  Bring up the point of the ripper at the other end of the inside of your buttonhole and cut.  Doing it this way prevents over cutting your buttonhole.  If you have a particularly long buttonhole you may want to do this in two steps, working from the edge to the center of the buttonhole.
