My children won't be involved. My 8 yo ds refuses to do anything crafty and the baby is too little.
I am making him a bathroom rug on the long loom and using a patchwork quilt top I made long ago to make a new shower curtain and painting his bathroom. Also making a little zippered bag for the shelf in there to hold his toiletries and filling it with a bottle of homemade aftershave.
I also want to use a plaid sheet I have to make him some new jammie pants and I made him an oven mitt/pot holder from a cool thrifted shirt that has a guitar print on it. Also, cutting up a pair of his worn cargo shorts and using the pockets to make him a "gig bag" to contain his tuner and capos and picks and assorted musical equipment odds and ends.
