Ooo perfect theme (I’m moving house on Monday!!)
I personally love original art- not just because I make it but because I think it makes a home a lot more personal & interesting. I also try & keep my artwork affordable as I believe everyone should be able to own a piece should they want.
How about something like the Shoal of Herring currently in my shop,
Or how about something even more affordable? A hermit crab literally carries his home on his back.
