Just a very quick post today - one of the cards I made for Inspiration Station last May featuring the Open Sea stamp. You can get 2 tri-fold cards out of an A4 sheet if you cut it diagonally. I made a mark at 5" on one short side and 3" on the opposite short side then cut between the two marks.
I took "bites" out of strips of Not Quite Navy card stock with a 3/4" circle punch to create the sea. The front of the card has two layers of sea so I could tuck one of the clippers inside it.
The Simply Scoring tool is heaven sent - it makes scoring even in thirds so much easier and quicker.
