1/4 seam allowance-A 1/4 seam allowance is a 1/4 inch of fabric between where your seam begins and the raw edge of the fabric. A quarter-inch allowance is used by quilters for most projects. Having an accurate seam allowance is necessary for making pieces that align properly when you assemble the quilt. Many sewing machines have settings or 1/4″ presser feet to help you sew with an accurate seam allowance. If you don’t have a 1/4″ foot, using colored tape to mark the correct allowance on the throat plate of your machine can help you see the proper allowance more clearly.
