Where to Begin
This isn't the whole site - it's the handful of entries I'd actually point someone to on their first afternoon with a needle and a machine, roughly in the order I'd want them read. Everything else here can wait until these feel familiar.
Vocabulary worth knowing first
A few terms come up constantly enough that it's worth learning them before anything else, so the instructions in every other article actually make sense on first read.
Tools to have on hand
You don't need a full workroom to start. This is genuinely most of what I used for the first year.
Take your measurements
Before you buy a pattern, measure yourself properly once and write it down. The Body Measurement Worksheet explains each measurement and keeps a copy you can print.
Techniques to learn first
These are every beginner-level technique on the site - the ones worth practicing on scrap fabric a few times before they show up in a real project.
-
Bias Binding

Cutting, joining, pressing and applying bias strips to finish necklines, armholes and raw edges - with strip-width formulas, two application methods, and fixes for rippling and missed stitches.
-
Dart

How darts turn flat fabric into a shape that fits a curve - the main types, marking, sewing a point without a pucker, pressing, and moving a dart that sits in the wrong place.
-
French Seam

A seam sewn twice so the raw edges end up sealed inside a narrow tube - the cleanest finish for sheers and lightweight fabrics, with step-by-step diagrams, seam allowance maths, and fixes for whiskers and puckers.
-
Gathering

Drawing up a long edge to fit a shorter one with soft, even fullness - how much fabric to allow, where to put the gathering rows, the cord method for long or heavy edges, and fixes for snapped threads.
Your first garment
Once those techniques feel familiar, this is the one I'd actually cut into real fabric for - simple enough to finish, real enough to wear.
-
A-Line Skirt

Drafting and sewing an A-line skirt - two ways to draft the flare, how much fabric to buy, fabric choices, and hemming a curved hem so it hangs evenly.
