I've already bought the sitting room carpet now so I'll just have to see how it goes. I wont be fussing too much as I like people to feel at home in a room and sure muddy boots would have been taken off anyway even with the old carpet.
I would consider scotchguard now that it has been made safer health-wise for a few years now.
Yes I did think of sisal to and your comments noted thanks Rustbucket and Slugbreath.
Bigbird I was pleased to hear about your research – I am inclined to do research before I buy anything and sometimes wonder at people I know who go out and spend just an hour or so deciding on stuff I would take months to decide. You seem to have got a great bargain – would like to know where you bought it. The 100% wool is great too as there would no “new carpet” smell from it, my new 80/20 in the sitting room smells strongly and am a bit worried about fumes for a relative who is to visit shortly who has asthma. I'm doing a bit of research on what type of houseplants absorbs the fumes and clean the air.
I'm on a house renovating project now on and off for over a year, currently getting some plastering/painting done outside and will keep hall/stairs/landing carpet simmering in the background.
Really appreciate all your comments.
