||A casing is created in window treatments to hold weight rods, to slide over a decorative pole… or to encase a rib. In clothing a casing may be used for encasing elastic, a drawstring or something similar. A casing is simply fabric folded over and sewn to create an envelope or tube to hold the item for your project.
||After you have sewn a curve, it is important to clip the seam allowances to allow the fabric to lay flat. For an outside curve (shaped like an upside down U) you need to clip the seam allowance to within a breath of the seam line. An inside curve (shaped like a right side up U) can be either clipped or you can cut very small notches (V shape) out of the curve itself in order to have it lay flat and not make bunches when the project is done.
||A twisted or woven “rope” or “string” that is used primarily in piping and to act as a drawstring in a jacket hood, waistband, or as stabilizer for frog closures. Cording is covered with bias strips of fabric when used for most decorative applications (such as edging a pillow). Other decorative effects can be achieved by zig-zagging over cording on a fabric for a raised design.
||A button covered with coordinating or same fabric as the garment for which it is being made. You can easily find buttons for fabric covering at your sewing store. They are in kits… and are fairly easy to use. Professional workrooms may opt for a button press and button forms.
||On a pattern, the outermost dark line is the line upon which you cut. Traditions vary; some people cut through the center of this line, others cut just to the outside of this line.
