There's a wonderful new exhibit a the DeCordova Museum, in Lincoln, Massachusetts. It's called "Trainscape: Installation Art for Model Railroads", and it's on view until Jan 13, 2008. There are a number of pieces in this show that use fiber a main element.
My most favorite piece is by Ralph Helmick. It's called "Fourteenth Way", and it's shows the illusion of snow covered mountains, that are actually made of cut white paper letters suspended by nylon thread. No matter where you stand, as the train runs through the mountains, it's as if it's going through a snow storm. I LOVE it!
Also on exhibit in a different gallery in the museum, are two pieces by Samantha Fields. One is "Wallpapered Space II", 2007, created with vinyl siding, yarn, afghans, and wall paper patterns stitched with yarn. The other piece is "Curtain Mother", which fills a sixteen-by-sixteen foot window with layers and layers of curtains. There isn't an image of this piece on the Museum's website.
