And here are some of my tricks to make a nice card on just 10 minutes:
Use a collection kit- someone made it for you and every single paper there fits all other products.
Cut some stickers apart, as I did with three small dot stickers and use them for you visual triangle.
Try to layer your papers and stickers with some 3d glue for a nice texture and dimension.
You can use the stickers set name on your projects as it's already glued, as I did with a word Passover on my card.
Ink! Ink your edges for a nice shabby look, use more then one ink (I used 3 here)
And last, but not least- learn to take better photos than I did (lol)
And here is a side view of this card
