Hello, I seriously need camera cases. Finding a large Halliburton case in an antique mall in need of foam (it had none at all) for $30 inspired me to grab a few $2 hardshell suitcases at the Goodwill. I have plans to gut them and convert them into camera cases and free up some drawer/cabinet space for other things. What is the best source for high-quality foam that can be cut as needed? Any particular brands/retailers about which you could share experiences? Thanks in advance.
