@HandcraftedbyPicto Hi Jan,
Fantastic questions – thanks so much! 
It’s great to chat about all of the details because I literally only had the core concept when I first posted on the forum, so I’m now being forced to think about all of the details, which is incredibly useful.
Regarding the content, ultimately, the sky’s the limit. However, in my experience it’s good to start small and focused, so the initial idea would be similar to a gallery. Once that was successful (i.e. there were enough visitors), then there would be opportunities to branch out and do interviews, write articles and all sorts of other fun things. As the gallery would link to your Folksy store, visitors could find out more about you there.
As for the advertisements, I personally really hate it when I visit sites and am bombarded with ads, especially irrelevant ones. If ads were shown, they would have to be minimal and relevant.
Are you familiar with www.wanelo.com ? The core premise as I understand it is that they are bringing together collections of great products. What I envision is similar, but only for handcrafted items. The site would be a gallery, but when you click on the product, you’d be taken to the person’s Folksy store.
In fact, I know people in this community already use sites like I am envisioning. For example, yesterday someone was kind enough to introduce me to http://craftori.com/ , which is very similar. However, I think there are things which could be done to improve usability, as well as get in front of a wider audience. A good comparison could be the mass media: even though multiple newspapers, magazines, TV channels etc all cover the same stories, they reach different audiences. In a similar way, I see the benefits of having multiple independent sites promoting quality craft, and ultimately bringing new and different visitors to your stores.
I’m not yet sure what specific affiliate opportunities there might be, but I’d love to clarify the concept in general. In a nutshell, an affiliate commission is a small amount of money paid to someone when they recommend a company. The interesting thing is that it is the company that pays this commission – the customer is completely unaffected and still pays the normal price. It’s easier to understand with a tangible example, so let me find one.
OK, the site www.craftsy.com has an affiliate program, so I’ll show you how it works. The blog ACreativeBeing is an affiliate with them and has a post about Craftsy classes. ( http://www.acreativebeing.com/2014/03/10/giveaway-craftsy-crochet-class/ ). When you click on the links in the post, you’re taken to the Craftsy site and, if you choose to sign up or buy a course or product, Craftsy will pay ACreativeBeing a small commission. The customer will not pay anything extra at all – the company (in this case Craftsy) will pay the person who referred the customer (in this case the blog ACreativeBeing) the commission. I’m not sure how much this particular company pays, but you could read about it here: http://www.craftsy.com/blog/affiliate-program/
Sometimes people can feel confused about where the money comes from for these commissions. In essence, companies have advertising budgets and so if, for example, a blog is bringing them customers, then that’s money the company doesn’t have to spend on other forms of advertising, so they can easily afford to pay a commission to the blog.
Affiliate relationships are extremely common these days: whenever you’re visiting a site, if you scroll right down to the footer, you’ll often see a link to join the site’s affiliate program. Also, you’ll see many blogs and websites have an affiliate disclaimer where they clearly state their policies around using affiliate links. Once you start looking, you’ll find these tell-tale signs everywhere.
Providing people are transparent and ethical about affiliate relationships, they can be a good way of earning a bit of money. Personally, I think the key is to only ever have affiliate relationships with companies who you would happily recommend for free anyway.
Hope that helps and please do ask any other questions you might have – it’s really helpful for me as well!
