Measurements Used:

If you would like to see detailed images of each of these measurements demonstrated on a model and on a sample pattern, please visit PatternMakerPro.

PatternMaker Pro

Each step in the instructions includes the category and name of each tool used, as well as its icon, for easy selection in PatternMaker Pro.

Values in curly braces {Center Length Back} are selections from a measurement set used in a formula. Values in square brackets are Measure Between Points tool selections ([Measure 1Center Neck Back to 4Armhole Ht]), also used in formulas. Always be mindful of parenthesis placement to force the correct math order of operations.

Movement / Direction

The instructions use X and Y to define direction.

X is horizontal movement. A positive X value moves to the right. A negative X values moves left.

Y is vertical movement. A positive Y value moves down and a negative Y value moves up.

Companion Patterns

This pattern goes along with the Basic Block Front 101-F1 and Basic Block Back 101-B1 drafts. I recommend that you open that draft and add this sleeve pattern to the same file. This allows you to make pattern modifications later that require all three patterns. Also, you'll need the front and back armhole measurements when drafting the sleeve.
