don't know the size of your prints but when I wanted some frames I went to Elsecar Antique Centre and got some old framed pictures - (very cheap) chucked the old pictures out and varnished the picture frames - looked as good as new.
looked at picture of some manky old sunflowers in a pot and another of what looked like a guy screaming and thought there's only one place for these pictures and that's in the bin!
thanks SD - seeing those pictures shows me I was right to bin them - there was a couple of others went the same way - A Laughing Cavalier by some guy called Hals and an over weight old geezer (flabby and naked) by a Lucien Freud -- looking at that each morning would have put me off my muesli.
