Here’s a “Cookies In A Jar” I put together for a birthday gift.  I used pressed leaves for the recipe instructions card & lid decor.  I can’t find the recipe I actually used (this is a photo from my archives) but here are a couple good recipes:

M & M’s Cookie Mix, Oatmeal Chip Cookie Mix, Hershey’s Cookies, and Sand Art Brownies.

Plus, here’s an article on how to make your strata layers look their best.
