Blogging is a must for artists, a great way to display your work, connect with your prospective buyers and collectors!
E-commerce bloggers can gradually choose to write curated content from other websites/blogs. That always helps because a buyer will generally not spend much time surfing. He/she will appreciate it if you provide most of what they are looking for.
Remember that content is the key to a successful blog. Quality scores over quantity in getting audience to your blog.
