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.
For maximum efficiency with cutting printables, consider in investing in a cutting tool like the Silhouette Cameo or Cricut Explore. Both allow you to print out any shape and cut around the printable. It takes minutes to set up the file and cut compared to hours of using scissors.
