## Understanding the sleevecap

In version 2 of FreeSewing, the sleevecap of Brian was redesigned to be more adaptable to
|
||||
different types of sleeves and garments. As a result, the sleevecap alone now has 20 options
|

to control its shape. Whereas that may seem a bit overwhelming at first, understanding how the

In our example, the front of the sleevecap is on the right hand side. But how would you know?

While patterns typically have an indication that shows which side is which (a single notch
|

means the front, whereas a double notch means the back), you can also
|
||||
recognize the front side of a sleevecap because it is more curved. The backside of the

sleevecap will also be curved, but it's a flatter curve. That's because the human shoulder

is more pronounced and curved on the front of the body, thus the sleevecap is more curved

While the sleevecap in Brian (and all patterns that extend Brian) have a lot of options, understanding how the
|
||||
sleevecap is constructed can help you design the exact sleevecap shape you want. To do so:
|
||||
|
||||
* Start with placing the top of your sleevecap
|
||||
* Then determine the inflection points
|
||||
* Next, use the offset to control the steepness of the curve
|
||||
* Finally, use the spread to smooth things out
|
||||
- Start with placing the top of your sleevecap
|
||||
- Then determine the inflection points
|
||||
- Next, use the offset to control the steepness of the curve
|
||||
- Finally, use the spread to smooth things out
|
||||
|
||||
What's important to remember is that you're only ever controlling the shape of the sleevecap.
|
||||
Whatever shape you design, it will be fitted to the armhole, meaning that its size can and will be adapted
|
||||
to make sure the sleeve fits the armscye. However, the shape you design will always be respected.
