Opening a sewing pattern envelope for the first time can feel overwhelming. Tissue paper pieces covered in mysterious lines, symbols, and numbers — where do you even start? This guide will demystify everything.
The Pattern Pieces
Each pattern piece is numbered and named. The grainline arrow shows how to align the piece with your fabric’s grain. Notches (small triangles or diamonds) help you match pieces together correctly. Dots and circles mark important construction points.
Cut Lines
Solid outer lines are cutting lines. If your pattern includes multiple sizes, the cutting lines for each size are marked differently (solid, dashed, dotted, etc.). Cut on the line for your size.
Fold Lines
A bracket or “FOLD” marking means this edge should be placed on a folded edge of fabric — you cut out the piece as a mirror image.
Seam Lines
Inside the cutting line you’ll usually find a dashed seam line showing where to actually stitch. The distance between the cut edge and seam line is your seam allowance.
