Building your own props for your own personal use is a very rewarding experience. I've learned quite a bit about carpentering ever since I started building my pack, I've also learned several other unrelated things. Sure having a pack is great but when you've built it….its a major accomplishment(not to mention you just saved a lot of money). Building something like this is going the extra mile, taking time out of your personal life to take on the daunting and frustrating task of creating something you've always wanted. Its doing more and expressing more then a lot of people would even think about doing.
