This guide teaches how to turn a well-fitting pattern into a block pattern, which is a sturdier base pattern made of thicker paper that can be used for future pattern modifications or creations.

It covers the steps of transferring the pattern onto manila paper, marking important points like darts and grainlines, and cutting out the block pattern pieces.

Instructional Steps:

1. Ensure you have a well-fitting basic bodice pattern that has been tested on your body.
2. Gather supplies: pattern weights, tape, tracing wheel, awl, notcher, pencil, and scissors.
3. Lay the pattern pieces flat on a large sheet of manila paper, using weights to keep them in place.
4. Use the tracing wheel to transfer the pattern outline and markings onto the manila paper.
5. At corners, use the awl to punch through the paper to create a crisp 90-degree angle.
6. Mark important points like darts, grainlines, and center front/back lines.
7. Cut out the block pattern pieces carefully along the traced lines.
8. Use the awl to punch holes at dart points and the notcher to create notches at dart legs.
9. Label the block pieces with necessary information like size, seam allowance, and grainline orientation.
10. Store the completed block patterns for future use in pattern drafting or modifications.
