I was a Stampin' Up! demonstrator for almost 10 years when I left in 2008. The only reason I left the company is because I had my first daughter and it was impossible for me to host workshops and prepare for them with a newborn.
That being said, it was also before I discovered the power of the internet and marketing my business online.
I hear you loud and clear that some of those blogs are amazing. Trust me when I say that they have paid a pretty penny for them. But, what matters most is that you are doing what you love, you share your blog with your customers, family and friends and you promote your blog. The marketing of your blog is probably the hardest part as you need to spend time finding your ideal potential customers, engaging with them and helping them. Then, as they begin to see your knowledge they will migrate to your blog.
The best piece of advice I can give you as a former demonstrator and now somewhat internet "savvy", use your blog to communicate with your tribe, build a network and become a resource. Post your latest projects with instructions. Ask what they want to see, what they want to learn. Is it a new technique? A new product? Different ways to use reinkers? The best way to do Two-Step stamping, etc.
Give them what they want and they will be back for more, tell their friends and build a relationship with you. People in general want to do business with other people they know, like and trust. By "giving" first, you create an instant friendship and connection and they will try to help you every chance they get.
If only I had known this 3 years ago, I would probably still be a Stampin' Up! demonstrator. I still have a craft room of supplies I like to "visit" every now and then. Some day, I can teach my girls to stamp and do paper crafts so I can get back to my first love.
Good luck!
All the best,
Ivette
