Yes, you can sell items as a hobby without registering as an official business entity in many cases. However, it's important to consider the legal aspects of selling items locally or online before pursuing this route seriously. Check local regulations regarding small-scale sales and ensure compliance with any applicable tax laws related to income generated from selling items as a hobby. Even though it may not be mandatory to register as a business initially, keep track of financial transactions and maintain records for tax purposes if necessary in the future. While selling items as a hobby offers flexibility, treat it seriously by investing time into crafting quality products and exploring marketing techniques that can help draw attention to your items.
