I'm always looking for creative projects for my youth that will allow them to process a biblical concept or idea using their visual-spatial and bodily-kinesthetic intelligences (translation: a creative artsy craft project that lets them use their hands!). Here is a cool idea I came across at a great website called Lifehacker. Not sure how I would apply this yet, but it seems to have great possibilities for numerous applications. Take old wine bottles and remove the labels:
Just spray them with chalkboard paint. After the paint dries, rub chalk all over the bottle and then erase it. This will "prime" the bottle and give it that old chalkboard look that you so love!
