Home Printing & Cutting Instructions:

Cutting on 2 Fabric Layers: Single pattern pieces are generated for paired symmetrical components (Cups, Cradles, Wings, Straps). Fold or stack your fabric right sides together into 2 layers to cut both left and right sides in one pass.
Cut on Fold: Pieces labeled Cut on Fold (e.g., Center Front Bridge, Back Band, Straps) should be placed directly against the folded edge of the fabric.
In your browser print dialog, set Scale to 100% / Actual Size (do not select "Fit to printable area" or "Fit to page").
Verify scale by measuring the 1 in / 2.5 cm Test Square on each sheet before cutting fabric.
For multi-sheet pieces (for larger measurements), cut along the dashed red line and overlap onto the shaded margin matching the registration targets (⌖).
