Quilting Terms and Acronyms

Why Bother to Compile This List?

Just like any other craft or profession, quilters have their own language, which you should learn to succeed. I have trolled the internet and books to figure out what some of these quilting terms and bizarre acronyms are and decided to share them with you as I find them. This list will grow as I find new ones or get input on better ways to define them. I will also endeavor to assist in how to apply these terms! I guess years of spelling in elementary and high school may have taught me something after all!

Terms will be listed alphabetically and defined. Acronyms will be listed after the terms and separately. Hopefully, this will be searchable. My amazing webmistress will hopefully help with that. If you see terms you would like to add, please comment!

Terms:

4P = Four Patch

9P = Nine Patch

Applique is the process of sewing one fabric layer on top of another to create a design. There are three primary applique techniques: needle turn, machine, and fusible.

Bias is when fabric is cut at a 45-degree angle from the warp and weft. Bias cut fabric has the most flexibility or the least stability from stretching. This cut is preferred when making binding for curved edges or tape for curved applique. Another example is when quilters make triangles, the longest edge is a bias cut. That is why many quilters prefer to make half square triangles two at a time, which minimizes the stretch on the bias.

Block is a group of fabrics sewn together in a specific design. Blocks are generally square or rectangular, but they can be any shape. Blocks are sewn together to make the quilt top.

Block of the Month (BOM) is a program where quilters subscribe to purchase the pattern and materials to complete one block of a specific quilt per month. Programs generally last from 5 – 12 months.

BOM = Block of the month

Border is the fabric sewn to the edges of a quilt center. Borders may be plain, pieced, and/or appliqued. Usually, they have straight edges, but they can all have decorative shapes, such as scallops.

BSS = Basic Sewing Supplies

Chain Piecing is sewing pieces together one after the other without stopping or cutting the thread between pieces.

DSM – Domestic Sewing Machine

Finished Size is the size of the block after the adjacent pieces are sewn to it. The finished size is generally 1/2-inch smaller than the unfinished block, which allows for 1/4-inch on each side for the seam allowance.

Four Patch (4P) is a square block generally consisting of four squares sewn together.

Half Square Triangle (HST) is a square block consisting of two triangles. HST may also be called triangle squares. These can be made in multiple ways. There three typical methods. 1) Sew two triangles together, which can be difficult as the long side of the triangle (hypotenuse) is a bias edge. 2) Two or more HST at a time, in which a diagonal line is drawn from corner to corner of a square. Two squares are sewn together on both sides of the drawn line. Then, the HST are cut apart on the drawn line. 3) Similar to the last method, a diagonal line is drawn on one square. Two squares are sewn together on the drawn line. Excess fabric is trimmed 1/4-inch from the seam.

Hourglass is a Quarter Square Triangle consisting of two fabrics.

HST = Half Square Triangle

LAQ = Long Arm Quilting

LQS = Local Quilt Shop

Nine Patch (9P) is a square block generally consisting of four squares sewn together.

Piecing is the process of sewing pieces of fabric together to make a quilt top. There are a variety of techniques within piecing: foundation piecing, English paper piecing, Strip piecing, chain piecing, curved piecing, etc.

Quarter Square Triangle (QST) is a relative of the half square triangle (HST) and has three variations: hourglass, quarter square triangle and split quarter square triangle (SQST). QST are made in a manner similar to the HST and usually consists of four small triangles sewn together to make a square. The hourglass has four pieces in two fabrics. The QST has four pieces in three or four fabrics. The split QST is a hybrid between HST and QST, where the square consists of two small triangles (QST) and one large triangle (HST).

QST = Quarter Square Triangle

Quilt is a sandwich of fabric, which typically consists of top, batting or filling, and backing that are stitched or tied together. Generally, a quilt has a binding around the edges to enclose the edges of the fabric sandwich. However, some quilts are made as an “envelope” so a binding is not needed.

Quilting is the process of stitching the layers of a quilt sandwich together. There are three primary quilting methods: hand quilting, machine quilting and longarm quilting.

Registration Marks are the printed characters in the selvedge of the fabric. Typically, registration marks include the fabric manufacturer, fabric collection, or fabric identification code. It also has a series of dots that represent each of the dyes used in the fabric. When looking for coordinating fabrics for a quilt, the registration marks are very useful.

Right Side of the fabric is the printed side of the fabric. For solids and batiks, this may be difficult to determine.

RST = Right Sides Together

Sashing are the fabric strips sewn between blocks. Like borders, sashing may be plain, pieced or appliqued.

Seam is where to fabrics are sewn together during piecing.

Seam Allowance is the distance from the stitching to the raw edge of the fabric. For quilting, this is generally 1/4-inch.

Selvedge or selvage is the tightly woven edges of the fabric, which keeps the fabric from unraveling. It is created by the weft looping around to create the next row of threads in the fabric. With the exception of batiks, this is where registration marks are printed.

SID = Stitch in the ditch

Sizing is a protective coating usually added during the fabric weaving process. It can also be added by quilters while piecing to minimize warping during sewing. It should be washed out before using fusible adhesive as it reduces the sticking capability of the adhesive.

Split Quarter Square Triangle (SQST) is a hybrid square block of a Quarter Square Triangle (QST) and a Half Square Triangle (HST), consisting of one large triangle and two smaller triangles.

SQST = Split Quarter Square Triangle

Stitch in the Ditch is when you stitch along the seam line. Since most quilters press seams to one side, the stitching is generally on the low side or ditch (side without the seam allowance). It isn’t always possible to stay on the low side, but the term still applies.

Strip piecing is when the long sides of strips are sewn together into strip set. The strip set is then cut into smaller pieces, typically perpendicular to the seams. This technique is frequently used to create nine patches, where three strip sets of three fabrics each are made, cut into smaller pieces, and sewn together into a square block with nine pieces.

Subcut, sub-cut or sub cut is a term frequently used in cutting instruction. It means to take the pieces cut in the previous step/sentence/phrase and cut them into smaller pieces. Example, cut one 2 1/2″ square. Subcut once on the diagonal to form two triangles.

TBQ = To be Quilted = Quilt Top

Triangle Squares – see Half Square Triangles.

UFO= Unfinished Object. Any project started but not completed yet.

Unfinished Size is the size of a block before adjacent pieces have been sewn to it. Generally, the unfinished size is 1/2-inch larger than the finished size, which allows for 1/4-inch seam allowance on all sides.

Warp are the threads that run the length of the fabric and are strung onto the loom. The weft is woven through the warp to create the fabric. When cutting fabric for quilting, the fabric stretches or distorts the least when cut along the warp and weft.

Weft are the treads that run the width of the fabric and created the selvedge at the edges when they turn for the next row. When cutting fabric for quilting, the fabric stretches or distorts the least when cut along the warp and weft.

Whole Cloth Quilt is a quilt made from one piece of fabric or lengths of the same fabric sewn together to appear as one piece of fabric. Whole cloth quilts typically have intricate designs stitched onto it.

Width of Fabric (WOF) is the width of the fabric measured from selvedge edge to selvedge edge. Quilting fabric typically measures between 42-inches and 45-inches depending upon the manufacturer. Selvedge edges are generally removed before use. Therefore, the usable width is generally 40-inches. Backing fabric is generally 108-inches wide. Some other fabric types, fusible and interfacing have a variety of fabric widths, so check carefully when purchasing.

WOF = Width of Fabric

Wrong Side of the fabric or back of the fabric is the non-printed side. For solids and batiks, this may be difficult to determine.

WST = Wrong Sides Together
