Size range has been written on the front. The pattern has been checked and corresponds to that sizing.
Each pattern is an original and not a copy, these may be removed from the paper envelope to checked for completeness, for the pattern pieces and instruction sheet.
Patterns that are not factory folded may have more creases than expected.
Factory folded patterns will remain in its original state with all pieces folded from when it was originally packaged.
Patterns discolour over time due to many reasons, this pattern may be darker in colour from when it was first released. Even if the pattern is factory folded.
Some of the used patterns, may have been cut by the previous owner, and may have pin holes, cut darts etc. and small tears or repairs, but will still be usable for your needs.
You may find that the older/vintage patterns are designed for the smaller fit, if a size guide is included on the outer packet, this will be included in the photos.
