In case you missed me on my friend Sabra's blog Sew a Straight Line, I was a guest blogger a while back and did a tutorial on how to make a wetbag.
I like wetbags because you can use them for more than just cloth diapering. Take them to the pool for wet clothing and towels. Maybe you have a little one who is potty training. This would be a handy thing to have in the diaper bag for any accidents. Much cuter than a plastic grocery bag, don’t you think? This wetbag ends up being 9” x 12” and will fit about 3 large cloth diapers, but you can certainly adjust the sizes to make a larger bag.
To start, you’ll need the following materials:
*Two pieces 10” x 12.5” cotton fabric
*One 4” x 14” strip of cotton fabric
*Two pieces 10” x 12” PUL (polyurethane laminated fabric)
*I read that polyester thread prevents wicking (leaking of moisture in the bag), so I usually use that if I have it.
*baby powder or tissue paper
Place on of the cotton pieces of fabric on top of that, ride side of the fabric touching the zipper. This is where the baby powder or tissue paper comes handy. The shiny side of the PUL is tricky to sew on—my machine sticks and it isn’t fun! So you can either place tissue paper on top of the shiny side of the PUL, or you can dab a little baby powder over the shiny side where you will be sewing.
Pin together. Using your zipper foot, sew along the side of the zipper, as close to the zipper as you can. You can see the dotted lines in the picture below—that is about how close you’ll be able to sew with the zipper foot.
Turn both layers over and make the cotton and the PUL even along the sides and bottom. Topstitch closely to the zipper. Repeat above steps for the other side of the zipper using the remaining outer and PUL pieces of fabric.
Set the bag aside for now. Let’s make the strap. Fold the 4” x 14” strip in half and sew 1/4” seam along the long side.
Open the seam and iron.
Pin the strap to the cotton fabric, preferably on the side where you would start to unzip (so opposite of how I did it—oops!). I think it’s better that way so if it’s hanging by the handle and you have to put something in there, you can unzip it much easier with one hand.
Take the two outer cotton layers and line up as evenly as you can, right sides together. So your PUL is pulled up and out of the way. Sew 1/4” seam down each side, making sure to catch the zipper at the top and also the handle that you pinned in. Leave the bottom open.
Now take the two PUL layers and also line them up as evenly as possible, shiny sides together. Leave the bag how it is in the above picture. So the zipper is on the inside, and the cotton layers are still showing the wrong side. The PUL and the cotton layers are NOT connected at all besides at the zipper. Sew along all 3 sides of the PUL, leaving the zipper side open. Since you are sewing on the non-shiny sides, your machine should work fine on this part without tissue paper or baby powder.
Turn the bag right side out by pulling the cotton layer down over the PUL layer. Tuck the bottom of the cotton layers and iron. Topstitch closed.
