If you are stuck for card ideas, especially for male cards, a good solution is to use the recipients age as the theme of the card.
1. Cut out the letters required for the age.
I used a fiskars alphabet and cutter, but you can print off templates and cut them out by hand, cut them out free-hand, or use a die-cut machine like a sizzix Big-Shot machine. Whatever works best for you.
Cut the letters out twice. Firstly from a piece of patterned paper, and then again out of a piece of plain backing paper.
3. Create a background for your letters.
I have used a piece of dark silver paper (12.5cm wide x 11cm high), adhered to the page on an angle.
On top of that is a piece of grey paper, which I ran through the Sizzix Big shot in an dots embossing folder (12.9cm wide x 9.3cm high) and then backed by a piece of red card measuring 13.5cm wide x 9.8cm high.
