If you'd like to create hand-lettered printables, consider taking a custom lettering class so you can edit your designs in Illustrator. Hand lettering is an excellent way to make a printable truly custom.
If you're looking for clemency instead of a loan, head over and check out the etters for misbehavior, social slights, workplace issues and personal apologies. The new forms can help atone for troublesome or delinquent behavior at work, school or in the community. These include apologies for graffiti, interruptions, tardiness, and violent behavior. I advise using these as launch points to give you ideas for more personal, specific apologies.
