Baltimore Album Quilt – Originating from the Baltimore, Maryland area in the 1800s, these quilts are made of a variety of elaborate appliquéd blocks with symbolic designs and were popular in the 1800s. They are also referred to as sampler or friendship quilts.
Backing – A quilt consists of three layers. Quilt top is either pieced or a single piece of fabric. The next layer is batting. The bottom layer of a quilt is a piece of fabric that is generally 4 inches longer on all sides, this allows for quilting on long arm machine. Backing fabric can be a single piece of extra wide backing fabric or a fabric of your choice which will be sewn together to the size needed. A few quilters like to piece their entire backing with scraps of fabric, always allowing for the 4 extra inches on all sides of quilt. Example, if quilt top measures 60×60, backing and batting should measure at least 68×68.
Backstitch – A stitch used to secure the stitch at the beginning and end of a seam by stitching 4 stitched forward, 4 stitches back and then proceeding with your seam. This technique is done to secure seam and ensure it does not pull apart during piecing or quilting of quilt.
Bargello – A type of quilt that creates movement by how the strips of fabric squares are sewn, usually of the same color going from light to dark.
Barkcloth – A type of densely woven cotton fabric, which is made from the fibers of tree bark found in tropical places. It was most popular in the 1950s and largely used in home furnishings.
Basting – Long stitches used to temporarily hold fabric in place, can be done by hand or by machine. It is used to hold all three layers (quilt top, batting and backing) in place when ready for quilting process. It is not necessary to secure thread knot on either end of stitch, it is merely a way to ensure that your project stays secure and does not shift. These stitches are removed once quilting is complete.
Batik Fabrics – Made by covering an area of fabric with wax or other substance to prevent the dye from penetrating into that area. Hot water is used to remove the wax. Batiks usually have a high thread count so you should use a #12 Microtex needle.
Batting – A light weight, warm product used between the quilt top and quilt backing, batting is used for quilts, wall hangings, quilted clothing and home décor. Batting is also referred to as Wadding. It is generally made up of cotton, cotton/poly blend, bamboo, wool, bamboo cotton blend. There are two types of batting: with scrim and without scrim.
Bearding – Batting fibers that poke through to the top of the quilt during the quilting process are undesirable. This is caused by bad batting and will create this effect on front and back of quilt. Bearding happens when fibers in your batting pull apart and migrate through the fabric fibers of your quilt. You will most often notice this after quilts first washing. This is why it is important to choose good quality batting.
Betweens – Needles made specifically to sew all layers together during the hand quilting process. Also used for hand sewing binding when finishing quilt. Short and thin needles that are used for hand piecing and quilting as well as sewing on the binding. The size of the needles range from 7-12, with the higher number indicating a smaller needle.
Bias – The length or width of woven fabric is considered straight grain, there is no stretch when on straight grain. If you follow the printed salvage on the fabric, this is the lengthwise of your fabric, perpendicular would be your width of fabric. The bias grain runs on a 45º angle to the selvages and has an ample amount of stretch, so it is less stable than the lengthwise and crosswise grain. You must be extremely careful when handling the bias, as cutting on the bias grain will cause inaccurate cuts.
Bias Tape – Pre-made strips of fabric in various sizes that are cut diagonally across the grain to give the fabric some movement so it will turn curves nicely. Used for binding a quilt.
Bias Binding – Binding that is cut on the true bias, which is helpful when binding a quilt that has curved or rounded corners.
Big Stitch – A type of quilting where sometimes colorful thread is used to make large stitches, showcasing a decorative effect. It was a great way for hand quilters to show off and embellish their quilts.
Binding – A strip of fabric that is sewn over the edges of the quilt after the quilt has been quilted. Binding adds extra strength and support to a quilt, and this is when a quilt is considered finished by many quilters.
Birthing a Quilt – A birthed quilt is basically a quilt without binding and involves layering the right sides of the quilt together (like the inside of a pillow case) and sewing around all four sides, but leaving a gap to turn through. Then you’d turn the quilt right side out and sew the gap closed.
Blanket Stitch – A simple embroidery stitch used to attach appliquéd fabric to a main fabric. Can be machine or hand stitched.
Bleeding – When color or dyes from one fabric transfers to another during washing. This is due to hand dyes or color saturated fabrics losing their dyes when they are wet. Most commonly seen when washing vividly colored fabrics, particularly purples and reds. Always best to wash colors separately before cutting and piecing.
Blind Stitch – A type of invisible stitching often used for sewing appliqué or binding by hand, but a blind stitch can also be done on a sewing machine.

A quilt block can be a single piece of fabric cut with a rotary cutter into a perfect square or a block that has been pieced using many pieces of fabric and sewn together using ¼ inch seam allowance. A quilt design unit generally comprised of multiple squares that are repeated and formed together to make a quilt top.
Blocking – When a block is not square, a process that requires wetting and pressing fabric to a proper square block. This is also done using steam to help stretch portions of your block to match other blocks.
Block of the Month (BOM) – A program offered by quilting classes, quilt shops, etc., where quilters make a new block for 12 consecutive months with the intention of sewing the block into a sampler quilt at the end of the year. You can find many BOM options online or even in quilt patterns.
Bobbin – A small spool of ether plastic or metal wound with thread; fits in the base of a sewing machine and produces thread for the bottom stitch - this links to the top stitch allowing a seam to be sewn.
