Used to work out sheets needed (and total handle length).
An extra paper patch at each handle attachment near the top — not every bag needs one.
What 1,000 bags need — the net quantity, with the order including wastage beside it (change the wastage under Advanced).

Artwork template for your designer
A true-size (1:1) PDF of each piece with the bleed (3 mm), safe area (5 mm), fold lines, glue seam and handle holes marked — so the artwork arrives at the right size.
Construction allowances are estimates — always confirm with a physical sample before final production.
