Unless you are already a somewhat skilled sculpture then you will need to invest in some tools and materials, plus commit a significant amount of time to learn. However sculpting is an impressive skill and will allow you to make substantial income from selling your work if you get good at it.
Unlike most types of art which allows you to create a single piece and sell multiple times through licencing or prints, sculpting you can only really sell one piece of work once. However you can increase the amount you make by documenting the creation and upload to YouTube and social media sites. You can also offer your services through online courses and tutoring.
There are many different types of materials you can work with including:
When you have created your sculptures there are a plethora of sites you can sell on including Facebook Marketplace, Etsy, Ebay, Amazon and specialist sites dependant on your chosen craft.
Sites to use
YouTube – Learn how to sculpt with online videos and upload your progress.
