Main Difference
The main difference between Quilt and Blanket is that the Quilt is a bedcover made of multiple layers of fabric quilted together, usually stitched in decorative patterns and Blanket is a type of bedding.
Quilt
A quilt is a multi-layered textile, traditionally composed of three layers of fiber: a woven cloth top, a layer of batting or wadding, and a woven back, combined using the technique of quilting, the process of sewing the three layers together.
The pattern of stitching can be the key decorative element if a single piece of fabric is used for the top of a quilt (a “wholecloth quilt”), but in many cases the top is pieced from a patchwork of smaller fabric pieces; and the pattern and color of these pieces will be important to the design.
In the twenty-first century, quilts are frequently displayed as non-utilitarian works of art but historically quilts were often used as bedcovers; and this use persists today.
(In modern British English, the word “quilt” can also be used to refer to an unquilted duvet or comforter.)
Blanket
A blanket is a large piece of soft cloth. The item is typically used to keep warm, while sleeping or lying down. A blanket traps the radiant heat from the user’s body, and instead of dissipating into the air, it warms the user. It also protects against heat being lost by the processes of convection.
