Is this West Elm sofa the kind of thing you are looking for? Or even lower to the ground? http://www.westelm.com/products/4227534/?catalogId=52&bnrid=3918508&cm_ven=Google_PLA&cm_cat=furniture&cm_pla=Sofas_+_Sectionals&cm_ite=West_Elm_Baxter_Sectional_Sofa_Cotton-Rayon_Ikat_Print_Feather&adtype=placi_src=17588969&ci_sku=4227534&ci_kw=%7Bkeyword%7D

I recently saw this episode of Ask This Old House where they demonstrated painting tiles - especially as a solution to get one through till an entire redo is possible. http://www.thisoldhouse.com/toh/tv/ask-toh/video/0,,20902001,00.html Looks like you are doing a great job!

Moss. Preferably the thick dense dark green kind of moss that looks like a carpet that grows on the north side of embankments where little sun reaches. How close is your nearest state or national forest or, in the alternative, the nearest dirt road with an embankment that gets little if any sun because of shade trees. Take a drive and/or walk and see what kinds of moss you can find and take some pics. A dozen or so pieces would likely be all you need to get it started because, with the right conditions -- shade and moisture -- it spreads. (Ferns like shade but usually do better with drainage. Moss likes damp but will not grow in a puddle.) Where you have windows, you could create a "view" : With a concrete planter (or on concrete pavers set a large clay planter) with a trellis with English ivy. Alternately, you could buy your own pieces of exterior grade plywood and use deck screws to affix them to the fence posts and horizontal supports of the fence and decorate them w/paint and/or planters and/or metal sculpted art --- get creative.

I think the brands you have listed are good! What colour were you thinking? How have you gotten the opportunity to import carpet? I hope it's not too expensive for you!
