No they're chocolate brown so i'd better stay away from from the nail polish remover...lol!!
Saying that, when we were decotating i dropped a paint brush with gloss paint on it and got a little bit of paint on the back of the couch at the bottom but because it was sort of hidden i used white spirit to remove it and it worked but i wouldn't try it on the arm...lol!
OMG just tried the hairspray half way through typing this message so i could say if it worked or not and it DID...DID...DID!!!!!!!
Thank you soooo much, thought it would never come off.
