Using a Seam Ripper....

1 Turn your project around so that you can see the back of the embroidery. If this is a real dress, you'll want to turn it inside out. It is important to work from the rear. If you work from the front, you can accidentally remove the fabric, which will eventually be visible. 

• For hand-embroidered items, it's best to put them back in the embroidered hoop.
• If your embroiderer still has a stabilizer attached to the back, you should tear it down before continuing.

 2 stitches with a seam ripper. First decide how many stitches you need to remove, then slide a seam ripper underneath those stitches and pull it upward at an angle to tear them down. The blade will be cut between threads inside the hooked portion of the seam ripper .

• You can use a pair of embroidery or manicure scissors. Just snip the threads using the tip to make sure the fabric doesn't get cut.
• If this is a large part of embroidery work only a few inches / centimeter at a time.
• If you are working with multiple layered embroidery pieces, start with satin stitching. 

3 Back to the fabric front. If this is a garment, just turn it to the right. Depending on the type of embroidery used to sew, you can also start cutting threads.

4 Pull the stitch from the front of the cloth. Slide a distal index down the stitch, then remove them. Use a pair of tweezers to cut the tweezers and cut out any other stitches.

•  If a stitch does not come out easily, slip it behind the fabric; It's possible that you didn't cut any stitches at all.
• Again, if you are dealing with multiple layered embroidery pieces, simply pull satin stitches.
