What materials would you use to make a touchboard for preschoolers to experience rough, smooth, prickly, sticky, hard, soft. Also what materials would you use to make sound boxes

What do you mean by sound box?

As for the various materials for the first part, the obvious that stick out to me would be

Rough - sandpaper
Smooth - plexiglass (to resemble glass but be safer)
Prickly - velcro
Sticky - duct tape
Hard - a metal plate
Soft - cotton
