Four-fold folio - how do I do it? Sort of a tutorial

Hello everyone and welcome to my channel. This tutorial might give you some ideas for making a folio of your own. The cover piece measures 18 7/8 inches long and 8 inches high Scoring the folio: With the outside facing towards you, and up, the right-hand side will be the edge of the inside front flap. Starting from this edge, score at the following marks (All in inches) 4 1/4; 4 5/8; 5; 9 1/4; 9 3/4; 10 1/8; 14 3/8; and the final score at 14 5/8 The finished folio is 8inches tall and about 4 1/4 wide. Hope this makes sense! Have a lovely day, and thanks for watching Jennifer
