for a little tactile fun...
grab an old shoe box...
cut a hole out on one side...
cut out two pieces of fabric, large enough to cover the hole...
cover the hole, from the inside, with the fabric... glue the pieces on the edges, overlapping them in the middle...
and you've got yourself a mystery box.
now, gather some items to put in there...
and guess, just by feeling, what's inside!
you can do it one by one and play a guessing game...
or throw a whole bunch in there and try to find a certain one...
and let the mysteries begin.
