When my kids were younger we made the cutest photograph as a gift for my husband for Father's Day.
This is a pretty easy craft to do. You just need a pair of scissors and 3 pieces of posterboard. One the first board, draw the letters "w" and "e". On the second, draw a heart. Then on the third, draw a "d", "a", and "d". Then draw the "supports" in the "e", "d"s, and "a" so that it will hold the center pieces in place.
The actual photo may help explain it better. By "supports" I mean the small pieces that you can see are shadows from the edge of the letters to the center piece. Without those, the center would just fall out.
You don't need to make them backwards or anything. You'll figure all that when you get outside in the sun. For now, just write them facing the normal way. Then cut out the letters.
Next, use a pair of scissors to carefully cut out the letters. Don't cut through to the edge of the posterboard, and don't cut through the supports.
Then head outside in the early morning or late afternoon when the sun will cast a long shadow. Have each child hold up a posterboard over their heads. You may have to rotate or flip them to get the letters facing the right direction, but that's much easier to figure out once you can see the shadows.
Then just take the picture! Make sure to keep their feet in the frame, because that's part of what makes this picture special. I still love to look back at their dirty ankles and pigeon toes now that they're older.
Once I took the picture, I had it printed as an 8x10 at Walgreens and put it in a cute frame. That was it! A simple but special homemade gift for Father's Day.
If you have fewer or more children than we do, be creative - you can change the words, combine "we" and the heart, or add in another heart before or after. There are tons of combinations you can come up with. Of course, it would be easy to do a mother's day version. Or just a generic "We Love You" for anyone special, on any occasion.
