Main purpose of selvedge is to hold warps and wefts together. It prevents fabric from ravelling. In machine loom a separate operation is required to finish the edges. Selvedge is usually much more compact than rest of the fabric. There are more warp yarns in the area of selvedge. 1. Mostly ply is used for selvedge. 2. Twist is more in selvedge. 3.Suppose body fabric is in a weak weave then the selvedge is stronger than the rest of the fabric.

Even Tacking Uneven Tacking Diagonal Tacking 4. Tailors Tacking: Start tacking using double thread of contrasting color, so that they can be easily seen. Tack through double layer of fabric along the seam lines using even stitches of � length apart, leave them as loop without pulling it tight. After completing, raise the upper layer of fabric slightly and clip the thread between the layers. So that the thread tuft, will remain on both the layers of fabric and remain as a guide line. This is especially used for marking details between patterns such as dart markings and pleat markings.
