Seeking advice on starting a bussiness

Hey everyone, I’m planning to launch a cutting board made from pure, natural Tamarind Wood (Puli Maram). The goal is to offer a safe, chemical-free alternative to plastic boards. These boards will be made from solid raw wood, only sanded smooth, with no polish, varnish, or glue — just pure, natural wood.

To be honest, I’m completely new to selling a direct-to-consumer product and have limited market knowledge beyond my local area . I’d love to get some guidance from experienced folks here. For those running small craft or e-commerce businesses — what’s one thing you wish you knew when you started? Any common mistakes I should avoid? 2,I plan to start with Instagram and Facebook. Are there other effective ways to reach people across India who might be interested in natural or eco-friendly kitchenware 3,Selling on Amazon India: This is my biggest doubt. How does it actually work for small manufacturers like me?

Is it worth starting with just one product?

Is there any advice?
