CUSTOM PATTERN MAKER - UNEVEN SEAM ALLOWENCE HOW TO

Creating Seam Allowences is almost an instant process:
Use the OFFSET command under the EDIT menu to draw the seam allowances.

SELECT the command OFFSET
SELECT the line you want to offset with the cursor
Click ENTER to stop SELECTing
TYPE in the size of the width of the seam allowence and ENTER
Show the computer which side of the seam line to offset by clicking the cursor on the outside of the pattern piece
Click ENTER to stop offsetting.

If you want uneven seam allowance:

Draw extension lines, using the SNAPTO sub-functions INTersection, NEARest, and PERPendicular, from the narrower width to the wider width.
Use those lines as TRIM lines and use TRIM under the EDIT menu to TRIM away the unwanted seam allowance.
