So here is my WETBAG TUTORIAL!!! And of course my picture(s) for the day of 2/4/12
But make sure you read the entire thing, I will change a few things the next time so just read it thoroughly for what I did, and also what I WILL do.
I started with just under 2yards of PUL (because they screwed up when cutting) And an entire cotton flat sheet for the outside, and an 18" zipper. PUL does not shrink so no need to prewash, but your outer fabric likely will so please prewash this!!!
I had to measure a bit differently than normal since my edges weren't straight, so I measured in multiple spots and just hoped it would be straight (it wasn't so I had to start over haha). At any rate, you want your PUL to be 18x19 when finished, so including about 1/2" seam allowance, you will want it to be 36x20"... You don't need to add any extra seam allowance on the top/bottom for hemming because PUL doesn't fray, so you don't have to hem the ends (yay for one less step)! When measuring and cutting, measure one long strip of 36x20, when folding and pinning, you want the bottom of your bag to be the fold, so there will be no seams, holes, or otherwise leaky spots, at the bottom of the bag.
You will want to mark on the "wrong" side... aka the NOT shiny side. It should be the side that feels like actual fabric.
Because your "sticky" side will be on the machine, you may or may not have issues feeding it through. if you do, just set a piece of paper between the machine and the PUL, you can pull it off later.
ADDENDUM: You should actually sew the zipper between the PUL and outer fabric.. so yeah, next time it will look tons better! Right side of the zipper facing the outer fabric, wrong/under side facing the PUL.
So my tutorial may not be the most clear and concise, it makes sense in my head lol. So contact me if you have any questions!
