this is a handy way to stop card board boxes splitting and other things
you will need:
corrugated card board
cut your card board to shape [make sure it is not longer than the skewers]
push skewers though the holes in the card board
cut skewers to length [you may want to use wire cutters]
tape over both edges of the card so the skewers dont fall out [use 2 layers of tape so the skewers dont fall out]
TEST IT !!!!!!!!!!!!
