Elements and Performance Criteria
- Prepare for calculations
- Calculate drape fabric requirements
- Work health and safety (WHS) requirements, including ergonomic criteria and personal protection needs, are observed throughout the work
- Fabric repeats are measured for customer selected fabrics and recorded
- Fabric width is checked taking note of any wider than usual selvages
- Finished length of window covering is identified from order
- Heading type is identified from order and fullness ratio is identified
- Number of fabric drops per curtain is calculated
- Length of each fabric drop is calculated based on finished length plus hem and heading allowances and pattern repeats
- Allowances for seams, hems, headings, drape fullness or heading type are noted on the work order
- Calculate lining and interlining quantities
- Width of lining and, where required, interlining fabrics, is noted
- Number of lining/interlining widths is calculated based on required number of drape drops
- Length of lining/interlining drops is calculated, including hem allowances
- Amount of lining/interlining fabric is calculated and marked on work order
- Procedures for minimising waste fabric are identified and used
