also found myself buying things for the box/container they come in. I do use the product but was more for the latter reason. Ha ha I absolutely had to reply after reading this, I actually read it out loud to my hubby (Who is a bonafied, extreme cardboard freak...no really he is). This was awesome!!!! we go to the local furniture store for very large pieces, and try the recycle bins right after tax season for the giant cardboard/cardstock signs (white on one side), found this out by accident, decided if i didnt get them hubby might just kill me (not really, lol). also the really nice strong light weight stuff is called "honeycomb void filler" here is a link about it from uline. http://www.uline.com/BL_1856/Honeycomb-V\\... thanks for a great post. loved it. kraftykat424: Awesome!!!! Thank you! Thank you! Finally, a reason not to hate tax season! And I checked out your honeycomb void filler link - argh! It's so expensive!!!! So much for cardboard being free. Maybe I can act pathetic and convince one of those companies to sponsor me and send some freebies. Yes. That's a good plan. I am in the midst of making a cardboard house for my kids 4 and 1. It is so fun i find myself thinking about how to extend and improve it all day. Its almost as if i become obessessed with it. So you can imagine When i found this page.... I am so happy i almost couldnt breathe. Thank you
