Excuse the horrendous pics, as usual as I was in a rush for card club!
This is a wiper card, lots of tutorials on YouTube/ Pinterest. I couldn't find one with the measurements I wanted so I made them up myself to suit a 5 x 7" envelope. If you watch a tutorial video and get the gist of the basic card here are my measurements:
two pieces of grey card 10.5 x 5" and scored at 2" and 4"
'wiper' is 4" x 2", marked at 2" and a diagonal score from here.
When things have calmed down I might actually have a go at some videos as I have to make card projects anyway, just that I don't like my speaking voice...

Butterfly is K&Co
Called a wiper card because it folds flat into an envelope and then when you open the card (by pulling each end) the butterfly slides up like a windscreen wiper!
