Using Instructables to increase traffic to your Etsy shop
While many people on this site would love to make the item themselves, there are also a large number of folks that don't have the time/materials/resources to make the project and are fine with buying it!
I opened my Etsy store, making jiggy, in early September of last year. I've listed golden snitch necklaces, lego necklaces, fold over clutches, and some embroideries - many of which are instructables. I've sold a good amount of stuff on Etsy, especially the golden snitch necklaces - it's been much more successful than I had ever thought!
As of writing this, I've got around 5,500 views on Etsy, and a little over 1,000 of them have come from Instructables. (edited update - as of right now I've got over 9,000 views and 1,800 of them are ibles!) That's the majority of views I've gotten from an external site! The rest of the views have come from Etsy search, my tumblr blog, stumbleupon, and random websites that have linked to it.
I'd say if you have a successful project on Instructables, why not make a few extras and open an Etsy store? It could be a good way to get a start on Etsy. And if you've got an Etsy store you'd like to promote, why not post an awesome instructable showing us how you make an item from your shop? Just make sure to link to your Etsy store in the instructable's intro!
I'm definitely going to keep turning my instructables into listings for my Etsy store and vice versa. It's been a great experience. :D
