Soak your ice block stick for a few hours. This will help you shape the bow without it snapping.
Gently manipulate the ice block stick to make the shape of a bow.
I used a tin can to help get the correct shape.
With a sharp knife make a knick at each end to attach the string.
I found this next step quite tricky.
Your string will need to have a knot at each end so it does not pull through the ice block.
It is important to make the string the correct length as this will help keep your bow taut.
Carefully slide the string into the knick at each end of the ice block stick.
I used a bit of tape to stop the string detaching.
Cut the end off a cotton bud and get yourself a target.
