Score flawless, crisp lines in seconds on invitations, envelopes, gift boxes, and other projects with this handy scoring board tool. Features easy-access storage compartments and includes an envelope guide and bone folder.INSTRUCTIONS: Place pre-cut cardstock on the scoreboard surface. For best results, fold your card so the score line is the outside fold and the bump is the inside of the fold. Align the cardstock with either the left or right side of the board depending on the instructions for the particular project. Hold the paper in place with one hand. With the other hand, hold the scoring tool at a 45 degree angle. Run the length of the paper from the groove at the top to the bottom of the sheet. You should have a perfectly straight fold line.
