Iron the fusible interfacing to all the edges of your pattern pieces. This seals the fabric edges and will prevent (or at least dramatically minimize) any fraying. Pro Tip: If your fabric is slippery, lay a strip of interfacing glue side up on your ironing board.
How do you seal raw fabric edges?
Glue your edges with fabric glue, seam sealant, or super glue. Purchase any one of these adhesives at a local craft store or online. Simply place small dabs of glue along the edge of the fabric. Use a cotton swab or toothpick to spread the glue evenly.
How do you keep fabric edges from fraying without sewing?
Fabric sealants are clear plastic liquids in a tube that seal the fabric edge and stop fraying without sewing. Fabric sealants, which are made by several different companies, are available in craft stores. To apply fabric sealants, trim any loose threads from the edge of the fabric.
