Of course! try to be creative and have a schedule for your blog posts so you can stick to write regularly. With interviews, promotions, giveaways, mood boards or inspirational posts, or simply write about you, or your daily, or your creative space, brings people to now more about the person behind your craft..
I've had a great experience and feedback since I'm blogging, and definitely it has helped me not only gain more views and sells in my shop, but also feel more confident while navigating the huge ocean of the handmade world!
The interesting part of blogging is that you can write about anything you want. But I recommend you keep always a link to your shop. I tend to write about different subjects, but creativity, friends, and the handmade world is always present, no matter if its a recipe, a short trip, or just some other craft or inside thoughts I wrote about..
