I'm looking to make some DIY diffusers for my lights to help blend the light a bit and maybe reduce some of the shimmer effect. If you had a choice, what material would you choose for a light diffuser? Seems alot of materials have pros and cons, but may just be a looks thing, or maybe more of a balance between how diffused the light is, and how well the light is transmitted. What are your thoughts? If you saw diffusers at your LFS of all materials lined up for the same cost, which one would you get?
