{{Main|Trapunto quilting}}

Trapunto is a sewing technique where two layers of fabric surrounding a layer of batting are quilted together, and then additional material is added to a portion of the design to increase the profile of relief as compared to the rest of the work. The effect of the elevation of one portion is often heightened by closely quilting the surrounding region, to compress the batting layer in that part of the quilt, thus receding the background even further. Cording techniques may also be used, where a channel is created by quilting, and a cord or yarn is pulled through the batting layer, causing a sharp change in the texture of the quilt. For example, several pockets may be quilted in the pattern of a flower, and then extra batting pushed through a slit in the backing fabric (which will later be sewn shut). The stem of the rose might be corded, creating a dimensional effect. The background could be quilted densely in a [[Stippling|stipple]] pattern, causing the space around the rose bush to become less prominent. These techniques are typically executed with wholecloth quilts, and with batting and thread that matches the top fabric. Some artists have used contrasting colored thread, to create an outline effect. Colored batting behind the surface layer can create a shadowed effect. Brightly colored yarn cording behind white cloth can give a pastel effect on the surface.
