I WANT TO CREATE A WEBSITE TO SELL MY FAIRY LIGHTS ON
Can you be more specific on what you mean by sell i.e. where you envisage customers coming from?
This could range from - You have a real world shop which is well known - to - You intend attracting customers via search - to - You are very busy on social networks etc. etc.
Bearing in mind that a website exists to fill a need, hard to make a decision without knowing both customer and your needs, intended (or required) volume of sales. Whatever else you think is relevant, not least the unique angle(s) you intend bringing to the market.
How to build a site is not a decision divorced from the purpose. Appreciate many approach the plan without that thought, possibly why 92% of new ecommerce sites are closed, or abandoned within 12 months.
