US Letter, A4 to A0 PDF
What is an A0 page format?
Size A0 is a copy shop format, which can be printed on a big plotter machine at any printing service locations.
Why make a sewing pattern in copy shop A0 page format?
Saves huge time in cutting and taping the pages together.
Layered PDF- patterns made in older versions of adobe reader are not layered. This A0 copy shop version makes your file layered, meaning each size is on its individual layer. You can choose which size to print, rather than printing all the sizes. Please Note: If pattern has same line types, meaning every size has same line type, then files cannot be converted into a layered one. It would be an A0 file with all sizes on a single layer.
Easy pattern storage :)
