Vellum Envelope

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!
