Another zippered pouch

Here is another of my purses recently made. I quite like it, but am disappointed that I used a vintage zipper to try and repurpose some older materials, however, after it was completed, I noticed that the zipper is a bit stiff. Any ideas on how I could make it smooth? I've heard of soap and also candle wax, and so far I've tried the soap unsuccessfully. Oh well. It smells very sweet now! If I can't sell this one someday I will keep it up my sleeve for something else.

I haven't yet had any labels made. So I've been inserting a little red grosgrain ribbon with white stitching inside the purses. I've realised that on the side you can't really see it very well unless you peek carefully, so I might have to try putting it somewhere else.

I'm also fond of the gingham lining. Happy with the old-fashioned but fresh look it's giving.
