I sell on ebay uk for about 5 months of the year.
I make doggie coats and when it cold or raining they sell really well.
But when i started there was only 3 sellers seling dog coats but now the competion is high with around 30 sellers seliing pretty much same thing.
Again it is addictive and can take up a lot of your time.
I'm not selling at the mo as i'm too busy on YT
