Usage Instructions:
Pattern Drafting (A)
- Trace your sloper (pattern with no seam allowance) and follow class/book instructions for pattern modification.
- Once the new design lines are planned, slide the ruler between the original traced line and the new marks until there is a graceful blend between the two. (A) You may need to slide the ruler more than once, marking only a small section at a time, until your new line smoothly transitions from the old one.
Altering Flat Patterns (B)
- Place marks on the pattern indicating the position of the new line.
- Slide the ruler to blend the old with the new. (B)
- Always mark from the stitching line and add seam allowance after the new line is complete.
Alterations (C)
- Fit the garment.
- On the wrong side of the fabric mark the pinned fit line.
- Follow the pattern drafting instructions above to slide the ruler from the existing stitched seam line to fit marks, until you have a new gracefully curved line. (C)
