What does a PDF pattern contain?

Each pattern is a PDF file with the sewing pattern formatted to be printed on home printers (either letter or A4 size paper) and  a tutorial with detailed step-by-step photos and instructions. 

Most patterns now contain an additional format of A0 if you would like to print on a large format printer, you can filter by A0 here: https://brindilletwig.com/collections/all?_=pf&pf_t_option=option_A0&pf_t_option_and_condition=true

Many patterns also contain projector files for using with a projector, you can filter by projector files here: https://brindilletwig.com/collections/all?_=pf&pf_t_option=option_projector&pf_t_option_and_condition=true
