Hey leatherworking community!  I didn't know about this site until the manager at my local Tandy Leather Factory outlet told me about it.  I just started getting into leathercraft in february and have only made two projects.  My first project was a disc golf bag that holds 3 frisbees.  This is my second project.  It is a costume piece backpack that was made to hold a 3l camelpak water bladder.  This piece evolved with every single step because, being unaccustomed with leatherworking, i was unsure how things would come together.  Here is a chronicle of it's construction.  Originally this pack was going to sling over one shoulder but i had to turn it into a more conventional backpack design.  This bag is going to be part of my costume for burning man this year 
 
 
Then i forgot to take a bunch of pictures in between this last one and the next 
I wetformed the closure flap to look like a leaf by letting it dry over pens which made the leaf spine effect.  I also had to glue a piece of heavier leather inside to hold the concho i used (it's to be installed into that hole punched) 
 
I used a couple different green dyes to get the effect of a more natural looking leaf. and added some quick designs into  the cross straps then painted them with a gold glittery dye

This is where i turned it into a backpack style 
 
As a backpack instead of a a sling it's able to support the weight of the water bladder (and 2 lightsabers :D ) 
 
 
 
As a final touch i tooled some orchids into the new shoulder strap.  This is dear to me because they are a copy of the tattoo i have  that the strap covers
