Raw edges in sewing are the cut, unfinished edges of fabric that haven’t received any treatment to prevent fraying or unraveling.
When you cut fabric, you’re creating these exposed edges along seam allowances, hems, and trimmed areas that naturally want to come apart over time.
Different fabric types behave differently – knits tend to curl and stretch while wovens fray in straight lines.
You’ll find raw edges wherever scissors or rotary cutters have sliced through your material.
These unprotected edges can cause problems like fraying threads, weakened seams, and even skin irritation from loose fibers.
Professional sewers know that proper edge finishing transforms amateur-looking projects into polished garments that last longer and look better with each wear, making them more durable and attractive, with a clear emphasis on preventing fraying and ensuring overall quality.
