The arts and craft business really is a good area to get into for those that love to make things. It's especially good for those that not only love making things but are running out of space to put the finished product! Why not sell those things that you love making and get some extra income.
The craft business is not likely to make you rich so if you are looking to make a large income this may not be for you. However, after doing some research on Etsy.com, I believe that it is possible to make a decent income that could definitely help a family out. If you've never looked around on Etsy.com then check it out for some great ideas to get your ideas going. You can also look at each individual shop and see how long those sellers have had the shop open, how many sales they have had, and what type of things they are selling best. To get a very general idea of how much those shops are making you can take the average price of the items that have sold, multiply that by amount of items sold and then divide by amount of years that the seller has had the store open. Of course, you need to take into consideration how much their supplies might cost and subtract that from the total. The possibilities of crafts are endless, here is an excellent ebook I found that gives you ideas of crafts that actually sell well or how to tweak your crafts to make them sell more easily.
I love to make crafts as well. This is an area that I actually am working on getting into. I love to paint and currently am specializing in children's wall art, check out my new shop (I'm still working on it) on Etsy. If you do get into this business, you don't have to sell on Etsy. You can build your own website and sell from there, go to craft fairs, put ads on Craigslist. If your craft is something wearable, you can have free advertising by wearing it, when people ask you where you got it you can have a business card ready to hand to them with your information!
