Suggestions For Storing Blocks Of US Stamps

I have several hundred blocks of 4 stamps ranging in size. Most are currently in glassine envelops in multiples. I'm not looking to display them, I'm looking for a better method to organize and store them. Some mint and some used.

Any suggestions besides glassine envelops would be helpful. Most of the envelops are #4 and they seem to hold 95% of the blocks.

My goal is to organize them according to their Scott #.

Thanks.

If you want to keep them in order and flick through them, approval/stock-cards are probably the simplest way.

That's true, stock cards would be easy to index. Thanks for the suggestion.
