A3. Custom (dense) quilting
Custom quilting designs such as those requiring extensive and precise ruler work is much more detailed and time consuming, plus it uses more thread and bobbins.
Custom quilting often includes stitch-in-the-ditch, outline work, ruler designs, graphically marking/measuring out spaces, detailed pattern transfers, use of templates, and other precision work.
This may include spaced formed feathers, pebbles (very intense), geometric designs, curved crosshatching, etc.
We charge $.04 per square inch for ruler work and custom machine quilting. A standard 80" x 96" quilt is 7680 square inches.
