Hi, I am a (very) small-time bag maker, I just recently started to make a go at turning it into a business. Part of my philosophy is to be open source with my patterns. Here is a link to my first tutorial, for a simple "gas tank" style bag. I would love any feed back on how it reads and if it makes sense! (the site is very much under construction, please excuse the spelling and grammar)
