Kayt had carefully planned presentation aids for her speech on "quilting." she thoroughly demonstrated how to sew together the squares by hand, which required her to concentrate on the quilt. what guideline for using presentation aids did kayt violate

I believe the answer is: Kayt focused on the presentation aid instead of the audience.
The purpose of a presentation aid is to enhance the audience's experience in the process of understanding the speaker's point.
Because of this, the aid should be made based on Audience's preference and limitation, not the speaker's.
