Each pattern file has 20 pages. Pages must be arranged in 4 row and 4 columns.
For all sizes (thus pattern files) the location of the pieces (back, front, facings) on the pattern sheet is the same, just as in the image above: sleeve is on top, back is on left, front pieces go to right and facings are somewhere in the middle.
Cut pattern pieces. You should end up with the following paper pieces:

Sleeve
Back neck facing
Back
Front – Top piece
Front – Side piece
Front neck facing
Front – Center piece
If you wish to make some pattern adjustment, for example narrow hips, this would be the moment.
