this is how i made some cheap-o reacher arms for an actor in my haunted trail. they were quite effective, in fact a woman had to be rushed to the hospital straight from the clown area-she went into labor!
Step 1: a little back-story first (you can skip this if you like)
we do a haunted trail, and one of our actors is a friend of my son. Dillon, the friend, is a BIG boy. last year his clown costume literally shredded off him. so we had to come up with something different. looking online, the Reacher costumes appealed, but we can't afford them... so i improvised with recycled items and ingenuity.
the pic is Dillon, holding my son Josh like a baby. like i said, he's a BIG boy!
