"Steve's Box" made popular by Andy (aka Andy's Box)
|
I should clarify my page heading.....this is actually an Original "Steve's Box" design made by me that i showed Andy how to make. He has been successful with using what i taught him and making NO modifications whatsoever to my original design. He has made roughly 100 of my boxes so far and it was time to share with everyone what i told Andy how to make a year ago. This page is to help others save money by making your own box or to educate you on not spending too much on this particular design.
