this exercise at Domestic Church to make a Jesse Tree of sorts (without the tree) into a Lenten paper chain. (download). The paper chain is made from strips of paper with each Day of Lent printed on it (at the bottom of the document -- just print the entire document and cut those days at the bottom into strips and create a paper chain).
Each day a child opens the day's link and reads the corresponding scripture verse which will take them from creation to crucifixion (I used the RSV bible). If you want to have the children draw the image that goes with the verse, go to the Domestic Church page and see each day's image. I had to make a few modifications because there were a couple of days missing the scripture verse, but all the images are there (I think).
I printed mine on plain old white paper because I didn't want to use costly paper to rip up every day. But if you have colored copy paper, go for it. Purple would be nice. I hung mine in the front hall with some fancy-pants-sticky-gunk.
If you have any questions, just leave me a comment.
