| Word | Description |
| Design Wall | A wall that is used to position and view your fabric and quilt blocks so you can see what your finished quilt might look like. Often a design wall is covered with flannel, so the fabric will stick to it without pinning. |
| Directional borders | Borders that have designs that run in a particular sequence or order. |
| Dog-ears | Long points that extend beyond the seam allowance. Usually this happens with triangles or diamonds, and it is a good idea to trim them so your quilt back has less bulk. |
| Double-fold binding | Quilt binding that is made from a strip of fabric that is folded in half lengthwise before it is sewn onto the quilt. It is also known as French-fold binding. Frequently you sew lengths of binding strips together using a bias seam. This is especially true when you are using bias binding. |
| Drag | Caused by the weight of the quilt pulling while you are sewing. Drag can result in your quilt being distorted when it is finished. |
| Drape - (or drapability) | How stiff or soft the fabric or quilt is. There are many factors that determine drapability: batting (wool and silk are the softest; high loft polyester is the most stiff); fabric (wool, cotton and flannel drape very nicely; polyester tends to be somewhat stiff); the number of seams and how much quilting (the more of either or both adds stiffness). |
| Drop | The part of a quilt that hangs down the sides of your mattress. |
