I know, right...!!! Tons of ways to go with this one! Here's where my pings took me:
Did you know that triangles are the strongest shape found in nature? Yep. It's because any added force is evenly spread to all three sides. Little bit of trivia for you today...
As you can see, I went 'conventional' with my cards.
For my birthday card, I used various scraps of papers to cut my triangles with MFT dies, as well as some MFT striped paper, a ME rectangle die, and a HA sentiment. Using the same size triangle as the blue one at the top, I cut four more from more scraps, added a 'hooray' from W&W for my second (congratulatory) card, all on an AE rectangle popped up on some fun foam to give it a bit of dimension. Two different cards for two different occasions using the same die on both cards. I wish you could see these in real life; they look pretty darn good if I do say so myself.
It's your turn now. I'd love to see what you make with 'geometric' shapes! Go forth and create!! I'm scheduled to have a cardiac procedure in a few days, but hope that it's just a quickie and that I can get to commenting on all your cards soon afterwards. Take care, and as always...
