Ok, here's how Ive been making the pyramid bags, if it'll help you guys..
First I wanted my bag to big a bit bigger, so I started with 2 fabrics, outer and lining that were 10x20 inches..and a zipper

(i had to use a diff zipper, bc i didnt realize how short that purple one was heh)
Then.. I took the lining and the outer.. and sandwhiched the zipper in between. The good side of the outer onto the right side of the front of the zipper. Sorry im not that great at explaining that part.. i just do it lol

here's both sides all pinned in place..

then.. sew the fabric to the zipper on both sides..

once you get both sides sewn together.. zip the zipper back up.. and turn it so the lining and underside of the zipper is showing.. fold it so the zipper is in the center..and sew the bottom.

I sewed a couple lines down, just to make sure..then trim..

Now.. unzip the zipper some.. and fold the bag so that the zipper is going down one side...this is the time to add a handle too. I put the handle about an inch or more next to the zipper at the top. You can see the ends of the handle sticking out here.. sew it across the top..

then trim and turn right side out..

and there you go...



I know my lining isnt the "cleanest" looking.. but, it works for me. One day I'll figure out a way to make it less messy looking.. but, I like it anyways. Hope this helps some ppl.
