Facing A facing is a method of finishing the raw edges of a garment or other sewn project with the application of fabric that is sewn on and turned to the inside, encasing the raw edges.
Fat quarter A fat quarter is a 1/4 yard of fabric, but is made by cutting a 1/2 yard into two pieces that are almost square (18 x 22) instead of simply cutting a 1/4 yard across the width of the fabric which would yield a 9 x 45 piece of fabric. The result is a more usable piece of fabric.
Feed dog This refers to the serrated bars under the sewing machine faceplate that moves your fabric as it is sewn. I dont know what dogs have to do with it, except maybe that they bite the fabric?

Fold line This is the marking on a pattern indicating that the line should be placed on the edge of folded fabric prior to cutting. This is used on symmetrical pattern pieces so that both sides of the pattern piece are cut the same.
Foot The foot is the shaped piece (that kind of looks like a forked tongue) that is attached to the shank of the sewing machine shaft that holds the fabric in place during sewing. In addition to the standard foot, there are many, many specialized feet for applying zippers, elastic, ribbons and other trims and for creating special stitches and hems.
French curve This is a type of ruler that is used for drafting specific curves on sewing patterns or designs.
French seam This is a double-seam construction whereby the raw edges from the first seam are sealed inside the seam allowance of the second seam. It works especially well on fabrics that fray easily. For a more complete explanation and directions on how to sew, click here.
