[SEE BELOW] I am not sure how to explain this part, but I am trying to stress the point that I am aware of accessibility needs for people with print disabilities (people who cannot read from printed materials) So I am not sure how to make it clear on the following sentence. When I design and create training media and instructions, I am aware about the importance of accessibility so I practice (or try to) prepare and create educational materials in alternative media to accommodate the consumers special needs.

Acutely aware of the importance of accessibility I practice in my spare time, developing educational materials in alternative media to accommodate these special needs.
