Block Paper Scissors

Learn three pattern hacks for the Alice shirt, by Anna Aguirre.

Posted in: Tutorials & Techniques • August 31, 2017






Block Paper Scissors is a monthly column that teaches three pattern hacks. These hacks help you give your Seamwork patterns a custom spin—all you need is paper, a ruler, and a pencil!

This month, we walk you through three different pattern hacks for the Alice shirt. Learn how to create a tunic version, shorten the sleeves, and change the neckline.

Note: For best results, be sure to make any necessary fit adjustments before hacking your pattern.

You'll Need:


  • Alice

  • Paper

  • Pencil

  • Scissors

  • Clear ruler

  • French curve



Create a Tunic

Step | 01


Cut along the lengthen and shorten line on the front (A).





Step | 02


Add 10 - 12” of space between the top and bottom portion of the front (A). You can add more or less length depending on your style preference.

Step | 03


Draw a perpendicular line out from the center front. Extend the line 6 - 8” away from the side seam at the hem.












Step | 4


Re-draw the side seam from the armhole to the hem line. Add a slight curve near the waist area. Re-draw the center front line.

Step | 05


Trace off the new pattern piece and label cut on fold.

Step | 06


Repeat steps 1-5 for the back (B).

Step | 07


Sew the garment according to the pattern instructions.

Shorten the Sleeves





Step | 1


Measure from your shoulder cap down your bicep to the desired length of your sleeve.

Step | 2


On the sleeve (C) pattern piece, draw a line parallel to the grainline from the circle at the sleeve (C) cap down as long as the desired length.





Step | 3


Draw a line perpendicular to the previous line. This will be your hem line.

Step | 4


Draw another line 1” below the line in step 3. This will be your cut line and hem allowance.

Step | 5


Cut along this line.

Step | 6


Sew the garment according to the pattern instructions.

Change the Neckline
















Step | 1


Repeat all steps in the previous section to create a 3/4-length sleeve. A 3/4-length sleeve should sit just above or below your elbow.





Step | 2


Measure down about 2 - 3” (or desired length) from the center front (A) neckline. Make a mark.

Step | 3


Draw a curved line from the shoulder to the mark, to create a new neckline shape.

Step | 4


Cut along this line.





Step | 5


Measure the length of the new front (A) and back (B) neckline. Draw a new neckband that is 2 1/2” shorter than this measurement.

Step | 6


Sew the garment according to the pattern instructions.
