They are SO into it this year.
We've traditionally been a pretty low-screen-time family. We closely monitor what films / shows the boys watch, and they don't play games on our devices. However, lately I've been letting the boys browse pinterest on the ipad, and the creativity this fires up in them is pretty remarkable. They tell me what they want to look for ("wooden train tracks that dads can make," "friendly monster muffins"), I do a search, and then they each have a board they can pin to.
Every night, they spend the hour before bed making some new Halloween decoration for the house -- last night it was cotton swab skeletons (they'd seen on pinterest) taped onto construction paper. For whatever reason, tape appeals to them much more than glue right now.
They go about this completely on their own, occasionally asking my help in tying a knot or cutting out really fine details. These are my favorite kinds of hours passed, where we all work happily, side by side, on our own projects. The pressure is off me to micro-manage some elaborate craft, and they're challenged by coming up with creative solutions to realizing their visions.
And usually, it's totally worth having to re-cap the markers and re-clean the paper scraps and pieces of tape off the kitchen table and floor eighty million times each day.
