Another option would be to have them made, I know that several garden centres/timber yards often have someone creative with wood who would love to make something up. I'm down in South Wales and a chap at a local timber yard/garden centre, that does sheds/fencing, makes some very nice stuff using tree trunks. https://www.facebook.com/TownAndCountryFencingandWelshtree?fref=ts

My friend has rich cream coloured blinds and they just have a grubby “smokers” look about them (God I hope she’s not on Houzz!). There are many different whites and some are textured so you can see the grain through without being dinghy.

Do you know how tall the armrests are? You want a table that's not much lower or taller. I think a round(ish) table suits well. I like Sonia's table and the whiskey barrel stool. But if you have the height of the armrests, we might be able to help you find some more options, if you like.
