It seems I'm always in need of a bigger bag. So, it came to my attention that making a new bag would be nice for carrying my books and supplies class. This bag is actually about 15" long by 12" tall and 2 or 3" deep. It's really quite handy. http://pages.slu.edu/student/corcoran/paint.jpg
I got this image from a link I found in one of the discussions here on Craftster. I'm not sure where, but thank you to whoever posted it! Basically, I just sketched it out in the white pencil, and painted it black. I changed it a bit from the initial clip art, but owe them the credit, nonetheless. http://pages.slu.edu/student/corcoran/straps.jpg
After applying fusible interfacing, I cut out squares on the bottom (for putting the bag together), and straps. For extra thickness, I used interfacing in on the straps too. I sewed them up to about an inch from the top of my fabric. http://pages.slu.edu/student/corcoran/pocket.jpg
For the linig, I used a solid black, but attached a pink pocket. http://pages.slu.edu/student/corcoran/pencilpocket.jpg
Because this bag is specifically for taking to my design class, extra sewing provides for pencil pockets. http://pages.slu.edu/student/corcoran/inside.jpg
Finally, pencil pockets and lining complete. http://pages.slu.edu/student/corcoran/finished.jpg
And it's finished. It's larger than it looks, and fits my textbook, supplies, and 11"x14" sketchbook.
If you've got any questions on how it was put together, feel free to ask.. I didn't provide much because I know there are some excellent tutorials already on Craftster:)
