Hello all, 
 
I'm new to this community and hifi in general, I can see I have much to learn.  I'm an engineer by trade and tinkerer in life, so I love build and learn about whatever I can.  In fact, I am planning to make my own variation of the stratokosster and have a question.  Can anyone recommend a cheap and readily available alternative to acoustic foam?  I do not wish to spend $20+ on the material if I can source an alternate immediately.  I am not familiar with the material properties of acoustic foam that I would be looking for, but I had considered the flat sheets of craft foam found in stores such as Joann's, Michael's, etc.  Would this be a suitable alternative?  
 
Thank you for all of your help and I look forward to becoming a member of this community.

Did anyone have any suggestions for acoustic foam alternatives?

Egg-crate shaped mattress topper foam might work for improving the sound of a room as it will both scatter as well as absorb incoming sound, but if you're looking for something smaller it might not work.  Just make sure it is open-cell foam that is pretty soft and it should work okay.

Thank you for your help. I was looking more specifically for the thin foam used in headphone mods such as:
