Do you love crafting? Whether you create one craft, or you have experience creating many arts and crafts, you can put your knowledge into a craft-themed website.
Your website can be your venue to share your knowledge, favorite crafts, tips, tools, and you can sell your own crafts and ideas.
If you are selling your crafts, you'll want to be sure to include good photos, because everyone loves to see what they are being told about, rather than just being left to imagine.
Another online venue for selling your arts and crafts is selling them on eBay -- easy, affordable, and they've already got all the traffic to their website you could possibly want!
You can also join affiliate programs and partner with merchants who can provide products and services that might be useful to your visitors, such as arts and crafts supplies. These products need not compete with your own products you are selling, if any, but rather can provide a valuable resource for your visitor, and even better can provide another source of income for you.
