I noticed in my post last night that pictures really would have helped to show exactly what I was talking about. So here goes.....
This is what your paper cut to 11 x 4.25 should look like.
This is the paper scored at 2.75 and 5.5.
Now fold along score lines and crease with your bone folder for a nice crisp fold.
Next assemble your card front, you can pretty much adapt any card front to suit this type of card.
Then attach a sentiment with pop dots, to give the card front a place to rest against.
Hope you're having a great day and happy crafting, Tina
