I decided to draw each unit's theme & "timeless truth" on a piece of foam paper. I had picked up a pack of multi-colored foam at the dollar store, and now I had a reason to use it! ;)
After we draw the picture, we cut it out & punch a hole in it somewhere. To decrease clutter, and because my daughter is not interested in wearing them out, we keep them all on one necklace-length string in our classroom. When we go to review, they are all together and they have a neat place to be kept.
Probably my #1 reason for doing it this way though was for sentimentality! I plan to use all the badges on the Christmas tree for years to come. A little bit of ribbon & a hook, and I have precious memories to hang on our tree!
Oh! And I just had an idea!!! Since there are 26 units, we may use this as an advent thing...Begin on the last day of November, choose 1 out of the stack, look up the scripture verse we chose to reference on the badge, and then hang that one on the tree!!! Hmmm....I think I like it!
Anyway, I hope this helps. :)
