1. Grain lines

These double-ended arrows tell you to place the pattern piece parallel to the selvage. Measure from the top and bottom of the arrow and ensure they are equal distances from the selvage. For example, if the top of the arrow is 4 inches (10cm) from the selvage, the bottom of the arrow should also be 4 inches from the selvage.

2. Fold lines

This symbol rectangular sewing pattern symbol has one open side and means place on the fold. Place your pattern piece on the folded edge of the fabric, making sure the selvages are even on the other side. If you are adding seam allowances, you do not add any to fold lines. Cutting on the fold ensures your pieces are completely symmetrical and is often a good way to minimize fabric consumption.

3. Notches

What do the triangles mean on sewing patterns?

Triangles and diamonds are called notches and indicate you need to mark these points to enable you to match up the pattern when sewing. Notches can be single, double and colored, or open.

I always recommend you cut outwards but this is a personal preference. See my article on how to cut notches for more information.

4. Button and Buttonholes

Indicate button and buttonhole positions. The sewing pattern symbols of a long bar with vertical ends represent the size and position of the buttonhole and a cross is common for the button sewing position.

Read my articles on sewing buttonholes by machine and how to sew a button.

5. Dots, Squares and Shapes

All shapes need to be transferred onto your fabric and are used for matching up pattern pieces and adding details. You can transfer with tailors tacks, chalk, or a removable pen. See my blog articles on marking tools in sewing and transferring markings.

6. Adjustment Lines (Lengthen or shorten lines)

These are double lines that are normally accompanied by the words lengthen or shorten here. These are quite common in sewing leotards and pants where length matters.

7. Stitching lines

Stitching lines are not generally found on multi-sized patterns but on single-sized patterns they are represented by dotted lines. Generally, there is no need to transfer these lines onto your fabric.

8. Darts

Shown as a dotted triangle or diamond, these show you where to stitch to add shape in areas such as the bust and waist. (Read marking darts, how to sew darts)
