I did these to bulk up my inventory for upcoming craft fairs.
I used this zipper pouch tutorial posted by someone at craftster.org.
The only modifications I did were to add a strap and to use a heavy interfacing for structure and durability.
All materials were purchased on the extreme cheap thanks to Joann’s super-duper fabric clearance. All were 80 cents a yard. The exteriors are black denim. I matched the outside felt and embroidery to the whimsically delicious lining fabrics.
