''To facilitate the pattern created in Valentina in being scalable, the wearing ease will be calculated as 20% of the arm_upper_circ. For example, a person with a measurement of 15" at the bicep would have a sleeve drawn by this method with 3" wearing ease.'' <br> <br>
The '''Wrist Line''' is drawn at a right angle to the Sleeve Centerline with half of the length of the Valentina measurement '''hand_palm_circ''' extending on each side from the center. This line is drawn at the wrist end of the Sleeve Centerline. By using the palm circumference instead of the wrist circumference, we will ensure that the sleeve opening is large enough for the wearer's hand to pass through. <br> <br> The '''shoulder_to_elbow''' Measurement would be used to place the elbow dart to shape the sleeve. Although the book describes adding a dart at the elbow, we will omit that from this tutorial because it does not add to the user's ability to learn to use the Valentina tools.<br> <br>
'''Figure 1-V''' shows the same drawing as '''Figure 1''', but shows the image as it will be presented in the valentina program after you have finished

The lines shown in the goldenrod color will not be printed on the final pattern. The lines shown in the black color will be incorporated in the '''detail''' steps to form part of the printed pattern.

The [[Formulas_McCunn_Sleeve|detailed instructions]] for the second half of the sleeve block pattern will create constructs to define the arm hole curve and the sleeve cap portions of the sleeve pattern.
'''Figure 2''' shows the special points used in constructing the sleeve cap portion of the sleeve.
