Acetate

Bit hard to photograph this one.

It's a sheet of printed acetate that I folded to make the card blank, then it just needed a topper.
Behind the topper, on the inside, is a piece of white card for the message - this means that the adhesive is sandwiched between the two and therefore not visible.

Because of the thickness of the acetate it was impossible to score so I just folded it over and then used a plastic roller to enforce the fold. I bought the roller in a DIY shop and I *think* they're sold to go over wallpaper seams, it's been so handy over the years when making my own card blanks.

Topper and acetate are both Papermania
