Stitching sequence: A designated order in which appliqué pieces should be stitched to the foundation fabric. Normally notated on appliqué patterns or pieces by a number.

Stitch-in-the-ditch: See "In-the-ditch quilting."

Straightedge: A ruler or other rigid surface that can be placed on template material or fabric to position a cutting tool or draw a line.

Straight grain: See "Lengthwise grain." (see more here)

Straight set: A quilt top setting with blocks aligned side by side in straight, even rows without sashing.

Straight-set border: A border that has been added first to the top and bottom of the quilt, then to the side edges, or vice versa.

Straight-stitch throat plate: A sewing machine throat plate with a small round hole for the needle to pass through. This allows less area for the sewing machine to take in or "swallow" the fabric as it is being stitched.

Straw needle: See "Milliners needle."

String piecing: Sewing multiple strips of fabric to a foundation piece for use in a block. (see more here)

Strip piecing: A process for accurately and quickly joining multiple strips, then cutting them into units or subunits for blocks. Also known as the strip method.

Swallow the fabric: At the beginning of a seam, the fabric edge is sometimes pushed into the throat plate by the needle and it appears that the machine has "swallowed" the fabric.

Symmetry: When one-half of an image or block is the mirror image of the opposite half.

Synthetic threads: Threads made from polyester, rayon, and nylon.

T

Tack stitch: A hand stitch used to secure appliqué pieces to a foundation. (see more here)

Take-up lever: The sewing machine part that holds thread and pulls it up as the stitch is being made.

Tapestry needle: A needle with an oval eye that accommodates thick thread and creates a hole in the fabric big enough for thick or coarse fibers to pass through.

Temperature: A relative characteristic that denotes the warmth or coolness of a color.

Template: A pattern made from paper, cardboard, plastic, acrylic, or other sturdy material used to cut pieces for patchwork or appliqué.

Template plastic: Easy to cut, translucent material available at quilt shops and crafts supply stores. Designs can be traced onto its surface with a marking tool to make templates, pattern pieces, or quilting stencils.

Tension: See "Machine tension."

Tension dial: A sewing machine component that allows for adjustment of the upper thread tension, important to achieving a balanced stitch.

Tension discs: Sewing machine parts that hold the thread and keep the tension appropriate for the stitch being sewn.

Tertiary colors: Colors that are combinations of primary colors (red, blue, yellow) and secondary colors (green, orange, violet)-red-orange, red-violet, blue-violet, blue-green, yellow-green, and yellow-orange.

Tetrad: A four-color combination of colors equidistant on the color wheel.

Thimble: A device to protect finger pads from needle pricks. Can be made of metal, leather, plastic, or rubber.

Thread-basting: Basting quilt layers together using a needle and thread and extra-long stitches that will be removed after the quilting is complete.

Thread count: The number of threads woven into a fabric. A higher number designates a more tightly woven fabric.

Thread finishes: Mechanical or chemical processes performed during thread manufacture to enhance the thread's ability to perform under certain sewing conditions.

Throat plate: The removable plate on the machine bed that covers the bobbin and has an opening for the feed dogs and needle. Throat plates can be changed depending on the type of project.

Tint: White added to a color or hue creates a tint of that color.

Tone: A color's intensity-its degree of lightness or darkness.

Tone-on-tone: Fabric that appears solid from a distance but has subtle areas of light and dark.

Topstitch: A machine straight stitch typically done on the right side of a project close to a seam.

Tracing paper: A thin, translucent paper used for copying patterns.

Trapunto: A method of adding raised texture to quilts by stuffing design areas. Trapunto often is used in stems, leaves, and other motifs.

Traveling (with the needle): Hand-quilting technique of moving from one area to another without knotting the thread and starting again.

Triad: Any three colors equally spaced on the color wheel, one of which usually takes precedence in a color scheme (yellow-orange, blue-green, and red-violet, for example).

Triangle-square: The square unit created when two 90° triangles are sewn together on the diagonal.

True bias: Intersects the lengthwise grain and crosswise grain at a 45º angle. (see more here)

Tufting: See "Tying."

Tying: Taking a stitch through all three layers of the quilt and knotting it on the quilt surface. Tying creates a loftier quilt. Also called tufting.

U

Unbalanced borders: Borders of different widths resulting in an asymmetrical look.

Unit: A combination of two or more pieces of fabric sewn together that form part of a block.

Universal needle: A sewing machine needle type with a point and eye suited for multiple sewing and quilting applications.

Vertical set: A style of quilt top in which the blocks are set on point in vertical rows.

W

Walking foot: A sewing machine presser foot with grippers on the bottom that act in tandem with the machine's feed dogs to evenly feed multiple layers of fabric and batting beneath the foot. Effective for machine quilting. Also called an even-feed foot.

Watercolor quilt: Quilt identified by multiple squares of print fabrics positioned so each color blends into the next, creating a watercolor effect. Also called color-wash quilt.
