i would make one, but since i saw it somewhere else first... i wouldn't want to trample on their toes. But its basically just the regular zippered pouch tutorial. But to make it look more fluid it did not cut the bag in half. I opened all the sides but the bottom, and work from there. So instead of sewing with 2 outter and 2 inner peices, I only had 1 outer and 1 inner. I think this creates a better look for it.
ok well i have a couple tricks. You can sew with the vinyl side down ( i don't like this cause i can't see the actual zipper when i'm sewing). You can actually put hair conditioner on the pressure foot and the vinyl (never tried it, but this is what the lady at the fabric store told me and promised it would work). But what i do is just slightly hold the pressure foot up white i sew, it's only a shory distance so it's not really a pain.
