  • Use a lightweight paper for liners so they can be assembled easily. Avoid using thick cardstock as it will weigh the envelope down.
  • Print one sample to check size, alignment, and colors. Adjust if needed and print another sample. Only when completely satisfied, print your complete set. Always print a few extras for damage or trimming / assembly practice.
  • Let your ink dry completely - usually just a few minutes - before handling.



  • Use a sharp paper trimmer to cut to size. Good overhead lighting helps. Clean the blade regularly to make sure there are no bits caught in - it will cause the paper to crinkle.
  • Use the crop marks on the paper as guides to help trimming. Cutters also often have size guides to help you line up your paper.

Pull back the flap.

Seperate the liner from the envelope flap - keeping the liner folded.

Run a tape runner alond the oter edges of the back of the liner.
