Patterns remain the property of Booby Traps and customers are not permitted to onsell the patterns or use them for production or classes or any other means of financial gain. Patterns are to be used by the purchaser only and not to be copied or shared. Customers are most welcome to make lingerie from our patterns for their family and close friends as a gift. Booby Traps thanks you for respecting the Copyright, as we have put many hours of hard work into these patterns.


Please be aware if you order both digital patterns and physical items to be shipped, your pattern will only become available when the order is shipped and completed. If you do not wish to wait for this it is advisable to make digital purchases in a separate order. Any bank transfer payments will not allow the delivery of the digital item until we are able to verify the payment has been completed.


How do I print a digital pattern?


Digital Patterns are delivered via the website for registered customers and via email for guest customers.



After completing your purchase, open the pattern from the link on your email receipt (if checking out as a guest) or log in to your account at the top of the homepage (registered customers only) and go to my downloadable products to open your pattern pieces. Simply click on the links - i.e A3 Pattern Pages and print your pattern pieces

Pattern sizes are mostly in A4 and A3 sizes with the exception of a few larger ones. All this information is noted in the product descriptions of each digital pattern so you can be sure prior to purchasing how you will need to have them printed.

A3 size is 497mm x 420mm (width x height) 

A4 size is 210mm x 297mm (width X height)

Print the Order Of Assembly in A4 sizing. Be sure you do not change printer settings and keep the pattern at it's original size to ensure a correct print out. 

Print the pattern pieces in A3 sizing (if applicable). This can be done on an A3 printer. 

Each pattern has a scale box that measures 6cm x 6cm to allow you check the proportions of the printed pattern.

We recommend printing pattern pages on an A3 printer and Order Of Assembly on A4. If you are unable to do this, and need to use an A4 printer, use the “Tile only large pages” in Page Sizing and Handling. Be sure the scale is the correct size by measuring the scale box. It will print on multiple pages.

For patterns that are larger it is recommended they are printed at a print shop. Your receipt email is proof of purchase to allow the waive of the Copyright.

All Booby Traps patterns are designed and labelled in Australian sizing and grading
