I was asked where I got the Vellum Envelope from a previous post. I made it as one of the Make 'n Takes at the providence Regional. Here is a photo of where to score and cut. Start with Vellum Card Stock cut to 7-1/4" x 7-1/4". Using the Simply Scored Diagonal Plate, score at 3-7/8" on opposite corners. Score at 2-7/8" on the other two opposing corners. Cut a triangular notch where the score lines intersect. This makes it easier to crease on the fold lines. I believe that directions were also included in the directions that came with the Simply Scored Diagonal Plate. Hopes this helps!
