Two-ply

In comics, the term two-ply refers to pre-bordered boards of 11 inch by 17 inch, commonly used by a comic book penciller in the creating of the individual pages for comic books. They often have a marked off art area which is 10 inch by 15 inch, which is the actual size of original comic book art. This format is larger than an actual comic book, and will get scaled down before it sees actual publication in an actual comic book.

The term 'ply' comes from the fact that the drawing board consists of two interwoven layers, resulting in a thickness made up of two layers or strands. It is sometimes referred to as a Bristol board or as Bristol paper.

2ply in the figurative sense
Two-Ply also means to have a second chance with someone, like having a second date after you broke up but then got back together.
