Zip-Itself Triangle Coin Purse

Here is my newest experiment in sewing. I am still deciding if it was a fail or not. :)
Here is my zipper coin purse. I used this free pattern from Craft Passion.

It is cute but sadly it is not very triangle shaped. :)

I think I used the wrong zipper. The teeth seem too big to go around the tight curves so it is not really unzipping.

This one is staying with me but I think I could get some good use out of it. :)
