Perfect to remove accidental errors! I own an embroidery company. I have embroidered someones design upside down on their handmade items. YIKES! Thanks to Peggy’s Stitch Eraser, I was able to remove the machine embroidery and correct the design. This is expensive, but it quickly paid itself off. It does take practice to use. The teeth are sharp and will quickly eat through the embroidery threat AND fabric. Just be mindful and know when to stop shaving, before you ruin the fabric. This beats picking threads apart by hand!
