Just thought I would share the Valentine's Day Bingo Sets that I made for my boys teachers. They are simple but I love they way they turned out. I found the Heart bingo cards online, deleted the numbers and printed them out. I handed stamped all the number, every card is different. I hand stamped and circle punched out all the numbers for the calling numbers. The hearts were also punched for the space markers. It is tied with seam binding. Each Bingo set has 10 bingo cards.
