Spring and Easter theme
The Easter themed side of this paper is a good size to cut each rectangle out for an USA A2 size card which is 4" 1/4" by 5" 1/2". That with a few flowers or butterflies and a small Happy Easter sentiment and you have a relatively quick card. It's challenging to find sentiments that work well with a small A2 card as many are too large. I'd pair this with a cut to dimension sheet of 12x12 paper of the same Spring theme as a card front.
