Here is what my class made last year. It was a pretty easy craft. We tissue papered the heart; just like I remembered doing in first grade. This took about an hour. (We did this in 2 days.) Afterwards, I spray mounted the hearts to large cardstock paper. Next, I called a small group of kids at a time to stamp the letters. After it dried, they added their names. Viola an instant card and gift!
These are cards that I am using for brain breaks with some of my students. But as the kids used them, the outer frame came apart. Instead of throwing them away, I am going to use them as picture frames.
Sorry for the grainy photo. Really bad lighting. But you get the idea!
