A quilt is essentially two layers of fabric with wadding sandwiched between. The top layer is the quilt top and the back is the backing. Those layers, with the wadding – also called batting – are held together by stitching or by ties.
That is the whole definition, and everything else is variation on it.
The three layers
The top is where the design lives, usually pieced from many smaller shapes.
The wadding provides warmth and loft. Cotton is flat and traditional; polyester is puffier; wool is warm and light.
The backing is usually a single fabric, and it is worth choosing something you like – a quilt gets seen from both sides.
What holds them together
Quilting is stitching through all three layers. It can be simple straight lines or elaborate patterns, done by hand or machine.
Tying is the quicker alternative: short ties at intervals through all three layers, knotted on one side. Much faster, and perfectly legitimate.
The stitching is structural as well as decorative – it stops the wadding shifting and bunching inside.
Where beginners go wrong
Many beginning quilters want to start with something ambitious, and it is the wrong instinct.
Start with straight lines and simple squares. A quilt made from squares of two fabrics teaches everything you need – accurate cutting, a consistent seam allowance, matching seams, and the three-layer assembly.
The skills transfer completely. Nothing you learn on a simple quilt has to be relearned for a complex one.
The two things that matter most
An accurate quarter-inch seam. Everything in patchwork depends on it. If your seam allowance drifts, blocks come out different sizes and nothing matches when you join them. Many machines have a foot specifically for this.
Accurate cutting. A rotary cutter, a ruler and a self-healing mat. Small cutting errors accumulate across a quilt exactly as seam errors do.
Start small
A cushion cover or a wall hanging rather than a bed quilt. Both use the same techniques at a scale you can finish, and finishing is what teaches you the assembly stage.
A great many first bed quilts remain unfinished tops in cupboards.
Fabric
Quilting cotton, which is a specific weight and stability. It cuts accurately, presses well and holds a crease – all of which matter.
Pre-wash it if you are mixing brands or using strong colours, so any shrinkage and dye bleeding happens before the quilt exists rather than after.
