##### Might vary slightly between preview and final result
|
|
|
|
For reasons that are surprisingly complex, there might be slight
|
|
differences in fonts and colors between how a pattern looks online
|
|
and how it looks as a downloaded PDF or SVG.
|
|
|
|
:::
|
|
|
|
## Lines
|
|
|
|
Lines (and curves) make up the bulk of marking you'll find on any sewing
|
|
pattern, including FreeSewing's patterns.
|
|
|
|
### Seams
|
|
|
|
Seams (the lines on which you sew) are indicated by a solid line.
|
|
The color of the line indicates the fabric type of the pattern piece:
|
|
|
|
<Legend part="fabricLines">
|
|
|
|
Seamlines for different fabric types
|
|
|
|
</Legend>
|
|
|
|
### Seam allowance
|
|
|
|
Seam allowance is indicated by a dashed line, that has the same width and color
|
|
as the seam they belong to:
|
|
|
|
<Legend part="saLines"> Seam allowance for different fabric types </Legend>
|
|
|
|
Note that the corners of the seam allowance are trimmed, and not extended:
|
|
|
|
<Legend part="sa"> A trimmed seam allowance corner </Legend>
|
|
|
|
### Grainline
|
|
|
|
Grainlines — a line that indicates the _fabric grain_ — look like this:
|
|
|
|
<Legend part="grainline">
|
|
|
|
A grainline indicator
|
|
|
|
</Legend>
|
|
|
|
### Cut-on-fold indicator
|
|
|
|
Cut-on-fold indicators look similar to grainline indicators, but point towards the line on which the fabric should be folded:
|
|
|
|
<Legend part="cutonfold">
|
|
|
|
A cut-on-fold indicator
|
|
|
|
</Legend>
|
|
|
|
### Dimensions
|
|
|
|
When you opt for a _paperless_ pattern, your pattern will come with dimensions:
|
|
|
|
<Legend part="dimension">
|
|
|
|
An example of a dimension on a pattern
|
|
|
|
</Legend>
|
|
|
|
### Other lines
|
|
|
|
Some patterns may have other lines on them, there are 4 additional styles:
|
|
|
|
- Note
|
|
- Mark
|
|
- Contrast
|
|
- Help
|
|
|
|
They might be used by patterns designers to add additional info, depending on the context.
|
|
|
|
<Legend part="otherLines">
|
|
|
|
Other line styles
|
|
|
|
</Legend>
|
|
|
|
## Line widths and strokes
|
|
|
|
Designers can, if they so choose, override the default line widths or set a specific stroke.
|
|
They might do that to add additional info, like where to fold a pattern, or the outline of where a pocket would go.
|
|
|
|
For reference, here are the different available line widths:
|
|
|
|
<Legend part="lineWidths">
|
|
|
|
The different line widths
|
|
|
|
</Legend>
|
|
|
|
And these are the different stroke styles:
|
|
|
|
<Legend part="lineStrokes">
|
|
|
|
The different line strokes
|
|
|
|
</Legend>
|
|
|
|
## Annotations
|
|
|
|
Annotations are extra embellishments on the pattern that further clarify the
|
|
designer's intent, help with construction, or otherwise provide value to the
|
|
pattern.
|
|
|
|
### Notches
|
|
|
|
There are two types of notches. The default notch is a dot in a circle.
|
|
|
|
An alternative style shows a cross in a circle.
|
|
This style is used to indicate the back of a garment.
|
|
For example, on a sleevecap you may see a dot and a cross notch.
|
|
This way you know which side of the sleevecap is the back (the one with the cross notch).
|
|
|
|
<Legend part="notches">
|
|
|
|
The default notch style (shown left) and alternative style for notches on the back
|
|
|
|
</Legend>
|
|
|
|

|
|
|
|
|
##### Why we chose these notches
|
|
|
|
In electromagnetism, a ⊙ symbol is used to indicate a flow of current coming towards you (to the front),
|
|
whereas ⊗ is used for a current moving away from you (to the back).
|
|
|
|
You can also think of an arrow. When an arrow flies towards you, you see its tip (⊙).
|
|
When an arrow flies away from you, you see its fletches (⊗).

### Buttons and Buttonholes
|
|
|
|
Buttons and buttonholes may come in different sizes, but always have the same shape that represents
|
|
how they look in real life:
|
|
|
|
<Legend part="buttons">
|
|
|
|
A button is shown on the left, and a buttonhole on the right
|
|
|
|
</Legend>
|
|
|
|
### Bartacks
|
|
|
|
A bartack is a stitch of varying size and length used to reinforce fabric. It is often used on the edges of seams such as at a pocket or fly opening.
|
|
|
|
<Legend part="bartack">
|
|
|
|
This is how a bartack displays on a pattern.
|
|
</Legend>
|
|
|
|
|
|
### Snaps
|
|
|
|
Snaps have a _stud_ and _socket_ part, and also look like the real thing:
|
|
|
|
<Legend part="snaps">
|
|
|
|
A snap stud is shown on the left, and a snap socket on the right
|
|
|
|
</Legend>
|
|
|
|
### Titles
|
|
|
|
Each pattern piece has a title that tells you the number and name of the piece, as well as the pattern name and a timestamp of when the pattern was drafted:
|
|
|
|
<Legend part="title">
|
|
|
|
Example of a title
|
|
|
|
</Legend>
|
|
|
|
### Logo
|
|
|
|
Some (or all) pattern pieces may also include the FreeSewing logo.
|
|
The logo has no special meaning, it's just branding.
|
|
|
|
<Legend part="logo">
|
|
|
|
The FreeSewing logo
|
|
|
|
</Legend>
|
|
|
|
### Scale box
|
|
|
|
The scale box allows you to verify that your pattern was printed to the correct scale:
|
|
|
|
<Legend part="scalebox">
|
|
|
|
The scale box
|
|
|
|
</Legend>
