TIP: The type of binding shown here is called double-fold or French-fold. It provides the most durable finish for a raw edge. The 2-1/2x42" strips used for this type of binding are cut on the straight grain of the fabric. Use the crosswise straight grain rather than the lengthwise grain for more give and elasticity.
Materials for Binding:
Enough 2-1/2x42" strips to go around all edges that are to be bound, adding some extra to allow for diagonally seaming and finishing the ends of continuous binding
1. To make binding for place mat, mark a diagonal line on one end of a 2-1/2x42" binding strip. Position and pin strips perpendicular to one another with raw edges aligned and right sides together.
2. Stitch along drawn line to join strips with diagonal seam.
3. Trim seam to 1/4".
4. Press open seam. Trim edges of seam that extend beyond edge of strip. Top strip shows seam pressed open; bottom strip shows diagonal seam from right side. This type of seam eliminates bulk in finished binding. If you have more than two strips for binding, add each strip in the same way as shown here.
5. With the wrong side facing up, fold over 1" at one end of the binding strip; press.
6. Press binding strip in half lengthwise with wrong side inside. The binding strip is now 1-1/4" wide.
7. Place binding strip against the right side of the place mat top along one edge, aligning the binding strip’s raw edges with the right side of place mat raw edge (do not start at a corner). Using a 1/4" seam, begin sewing the binding in place 2" from the folded end.
