Hi again, I have one other question, please...... :bluesmile

I am making some zippered bags, that are 2 layer - they have a waterproof lining with a cotton print outer layer. So they are for wet things and I don't want anything to be able to seep through the waterproof lining to the cotton layer.

I have been double stitching the waterproof layer, to prevent the wicking, but wondered which would be better?- doing a topstitch then a zig zag or 2 rows of top stitching? Or I am totally open to other suggestions, as I am new to sewing and am just guessing on what is best!!

Thanks again for your help!

I believe there is a product you can buy to water proof the stitched area.

You can get Seam sealer in the camping supply area of most Dept. stores.

Is there a sewing method that would be best, if I didn't use the sealer?

I already bought some seam sealer from the camping section at walmart, and hated it, plus I dont think it was going to waterproof it anyways.... and it left a strong smell!

Thank you!

I'd suggest using double stitched, with long stitches, so that you don't put as many holes into the fabric. I have a seam seal tape that you iron on over the inside of the seam once its sewn and it works fantastically. You use a teflon ironing sheet and a hot iron to seal it, it almost melts it onto the fabric and it doesn't come off. I did my son's snowboard jacket with it and a motorcycle rain suit as well. I've seen it a few places, but I'd think that anywhere that sells outerwear or waterproof fabric should carry it, unless its Walmart, or Fabricland. I don't think I've ever seen it at Joann's either. It's more of a specialty item.

Not only are you putting holes in your fabric, your thread is not waterproof. The only way to seal the bags is to seal them with a sealant. As far as the stitch, it depends on how much weight you are going to put in the bag. I would triple stitch something that would have weight in it and then I would seal the seams...because you'll have a lot of holes. People sometimes will sew the seams and then apply a plastic type tape around the bottom like you would sew bias tape seam binding with a long stitch. This helps. However, to get the best water proof bag.....seal the seams.
