We have several pattern and color combinations to assemble, mix and match for smaller size folded cards and envelopes. These can be a beautiful way to present gift cards or use the envelopes on their own for myriad purposes. If sending the patterned envelopes through the mail, you might need a mailing label (see coordinating standard labels in packaging). You can use standard weight paper or a cardstock for the envelopes, depending on the feeling you want.
