I have a tip for making quick and beautiful cards!!
Look for papers that are already well established for your base of your card. For my card I started with this sheet of My Minds Eye paper from the Jack and Jill Kit.
Then I cut the base to 4.5 x 5.25 and used the lower left and the upper right portions of the paper. Then I simply played up the elements that were already there, added a few embellishments and sentiment and then I was done! Easy peasy!!
