This year In steps Pinterest with lots of crazy ideas. Many were more wasteful and expensive than cheap cards. I finally found one that was both cheap and something they might use or keep. Valentine message clothespins. You may have seen them with the painted envelope and little fold out message? So I adapted a bit and came up with my own that cost me practically nothing to make.
Next, a bingo dotter in red leaves the clothespins with a lovely red stain. Why I have these in my house I am not sure, but they get used all the time for all sorts of crafts.
Then comes the white out and sharpies. Color in a little white rectangle near the opening end of the clothespin to create the envelope shape. Trace around the shape with a sharpie in black. Add inner lines and, using a fine tip sharpie, some dashes to the top envelope fold.
Finally add a little message (to/from can go on the back or top), clip in a sucker and your kids are ready to hand out a cute little treat with no paper waste!
