Why do I need
It is the extra material needed to prevent the seam from fraying and eventually coming apart. If a garment is sewn together without seam allowance, it will no longer be the correct size as the line of stitching will encroach into the fit of the garment, therefore making the garment, not the intended size.
ePatterns not have seam allowance?
ePatterns are predominantly used as a template to create new designs or styles, specifically using our online video tutorials. Changing any block to create new styles can alter the block dramatically, therefore, existing seam allowances might no longer be correct, and can become confusing. Typically seam allowance is added to a block or design once all amendments or design elements have been completed and the new pattern is ready to be sewn up for testing or toiling.
