Borrow Threading wooden Fruits

The fruit is smooth, solid wood, brightly colored
The hole is very large and smooth all the way through (no snagging)
The fruit is a nice size for cupping the hand around and works well with hand-over-hand assist
The cord is about 54" long and will hold all the fruit at once if you want
The cord has a 4" wooden "needle" on one end and a 1.75" wooden piece tied onto the other end to keep the fruit from slipping off
The cord does not collapse as you are attempting to thread because the needle is so long
The needle and hole are big enough for those with poor vision or hand skills to still be successful
The stringing involves a multiple step process that coordinates the use of both hands, and then unstringing reverses it

Try this:
Place the fruit in a container and ask for a specific piece each time, such as get an apple or get a pear, etc.

Ask the individual to turn the fruit in-hand as he looks for the hole.

String a sequence of two or three different pieces and repeat

Take the fruit off
