Work from the finished square
Mark the intended finished edge and centre line on a separate guide layer. Ask for the production template before adding bleed; hem allowances depend on the agreed fabric and finish.
Look at the corners
Fold a paper mock-up diagonally. A logo tucked into a corner can disappear in a knot, and a narrow border can look uneven after hemming. Move or resize those elements before sending the proof.
Send a reference alongside the file
Keep an editable master and a flattened visual reference. Label the colourways and identify any colour-critical areas. Confirm the file format, profile and required resolution for the selected print route before transferring final artwork.
