I'm still not the biggest fan of it, but things improved considerably once I sharpened the awl I was using! Most awls are dull as hell when you buy them - especially when ordering from larger companies. I'm still learning how to sharpen properly, but this tutorial from Armitage Leather helped me out considerably: I used this sharpening stone and some oil to sharpen mine, and finished it on a leather strop to smooth it out. You want your awl to be sharp and diamond shaped. You can use an awl by holding your work in a stitching pony (or your hands, if you're brave and well coordinated. Make sure to use the cardboard underneath - if you don't you will damage and blunt the awl in no time. Regardless of the orientation of the awl, you need to push it through as straight as possible to make sure your stitching looks nice and neat later.

This instructable will cover the details of the Vertical Garden built for my "Hydroponic, Automated, Networking, Climate Controlled Greenhouse Project".
The vertical garden is a space saving way to grow up to 72 small plants (such as lettuce, spinach, strawberries and lots of different herbs) all with the plant health benefits of hydroponics. The Vertical Garden is designed with modularity in mind, to be brought into the greenhouse and installed as a single unit, with only connection to the existing plumbing required before you're ready to grow. The installation of additional Vertical Garden units should be quick and easy. Other Instructables that cover elements of the "Hydroponic, Automated, Networking, Climate Controlled Greenhouse Project" are listed below with many more to come: Part 1: Construction of the GreenhousePart 2: The 72 Plant Vertical Garden As of this moment the greenhouse's skeleton is all that is completed.

So I found a simple alternative.

Creating your base I have created a wooden base that is tall enough so that you can get pictures of the lower portions of whatever it is you want to model and does not capture your background. After cutting all of your pieces of wood you will need to make your bottom and back of the base.I have attached the plans the I used. 2.
