My kids love paper. Line, unlined, heavy card stock or (usually) stolen from my printer -- this medium is cut, colored, scribbled, folded, taped and glued into an array of wonderful new items. Currently my kitchen table is littered with a beautifully designed paper bag (the two sides taped together) and two ink drawings: a monster and a woman are placed haphazardly near one chair.
I love that my children are following their muse and making items that show their creativity. It's fabulous to watch their minds work through problems and develop individual solutions.
