I love love love letterpress. It has a vintage feel with raised here and there with texture. The high quality cotton paper used in most adds texture to the entire piece (tiny dimplings on the paper with a rough feel all over).
Now and then I scour the Internet for letterpress wall prints.
Another of my favourites is from porridge papers who have this glorious yellow and white letterpress background with a print of a bug. I haven’t bought it because I’m not keen on the centipede. $25.
