(I apologize about this topic not relating specifically to lighting. Apple boxes are great for seating subjects in lit studios, and I know what I am presenting can be of use to many studio beginners here. Heck, I've "junstin-clamped" a small flash to an apple box before via the box handles, so in a sense it can make a sturdy, low-to-the-ground "light stand"!)
I'm presenting a little tutorial I put together for those interested in creating their own apple boxes at a fraction of the price available via market. These boxes are not available to me locally, and I had no interest in shipping 4 boxes to me at $200. (as quoted by B&H)
I love being outdoors and working with wood. Experience in woodworking is an asset to doing this as it will save you from making mistakes or from potentially getting hurt.
I really don't care for most photography DYI photography concepts. Making my own apple boxes, however, seemed like a rewarding and enjoyable experience. It has been. I've made 12 of these so far and they look great and work great. I'm even selling them on our classifieds and making a little pocket change out of it too.
Here is the link to the printable tutorial I made. (PDF ~0.5 MB)

Besides the necessary tools, nails and glue, you only need to spend $20 on an un-finished 4' x 8' plywood board. I went the next step and spent $43 on the "one-side-finished" board for a more professional look.
Here is a sample photo of how the box will be pieced together. Of course, the final version will have rounded/sanded corners.
