The first one, on the left, is for bag linings. It combines the lining with the wadding. As far as I'm aware, only the cream is available here. In theory, it makes the bag making process quicker as you're cutting and sewing the lining and padding of a bag together. Have you tried it? Would you try it again?
The one on the right is a film you iron to fabric to make it waterproof. It's been around for a while, but it's the first time I've bought any. If you've used it, did you like it? Would you recommend it?
I shall be testing them out this week and will let you know what I thought.
