I think I'm going to attempt replicating this bag.. Sans Hermes though because I would have to sell my car to buy a Birkin -- OR MY SOUL! AGH. Well I will attempt with this purse that I found at the Toronto Clothing Show last year at one of the vintage stands.... although the shape itself spikes might be overkill and flat studs might look better.
There are a bunch of places that have flat studs / spikes that you can attach.. and Youtube videos on how to go about attaching them to leather.... and a promo for their website to buy the studs http://www.studsandspikes.com. Pretty awesome I might add... I'll have to experiment with my bags one of these days and will report the results.
You can buy a bag of 100 flat studs for less than $25... just bought myself 2 bags, one with spikes and one with flat studs of 100 for $47CAD with shipping 🙂
