DIY Brock String requires only approximately a 4 foot long string, 4 beads and an optional paper clip that can be used to hold the string with the outstretched hand. Tie the ends of the piece of string together after you have strung on the four different colored beads. The larger beads seem to work better (1/2″) for this. Then you can tie the end of the string on to the paper clip.
Directions will vary based on the activity you choose. Refer to your therapist for additional details.
By the way, we added another picture of a vision activity entitled I Spy 3D that you may find helpful for your clients. Time them as you ask them to point out different items or see if they can recall them once you have removed them from their sight.
