I have no idea how to make 3d creations, but if I did, I would make an army of sloth friends!!! I think it is time for you to make an army of sloth friends and sell them. People like myself would buy an army.
I have been working my fingers to the nubbins trying to get ready for my first big show, http://funkyfinds.com/events/springfling/2011/. I am going to take all OOAK skirts. These are some of the a-lines I have started making. Some I am taking. Some I am keeping. Some have a small imperfection and I am selling before hand. Some are applique. Some are machine embroidered. Some are apron skirts. Most are baggy and bustled in the back with a drawstring waist to make it fit many sizes....
I have been working my tail to the ground to get ready for http://funkyfinds.com/events/springfling/2011/!! First year as a vendor and I am trying to take all 100% OOAK, no duplicates!! So excited! So, I am making circle skirts up the yingyang. Some are new fabrics, some are upcycled. Some I have that one minor glitch so I am selling before the show. Some are so awesome I have to keep them. Some are plain, some are intricate. Hope you enjoy
I had the same problem when I made some snack bags and sandwich wraps for my daughters to use for school. I opted for rip-stop nylon as the interior fabric and a cotton on the outside. I haven't heard anything negative about the use of nylon (yet) so all is well. The nylon is water-resistant, not water-proof, so we have stuck with mostly dry items. They wash and line dry very well!
I love the idea of zippers. I used velcro and the crumbs in the loops drive me nuts!!!!!!!
