Here is a simple mother's day card you can make with just a few different types of paper and some metal pieces you can find at Michael's.
Pick your papers- have a common color scheme and at least one with a pattern.
Cut a series of scalloped pieces to span across the card, cut another strip to go across the bottom, and tear a third piece to cut diagonally across the card.
Arrange your papers, and then glue them on starting from the bottom layer and working up. Use super glue for any metal pieces.
Finally, add your message :) I think that a hand made card is such a nice way to say happy mother's day!
