These pieces of art, made perfect for your wall, were created out of cotton and felt and other fabrics. They're part of an exhibit called "Sew Nerdy: A Geek Craft Extravaganza", so these pieces will be on show until August 11.
Unfortunately they run from $US60-$US100, which isn't too terrible, but not enough for me to warrant as a wall decoration purchase. Particularly because my mum is quite skilled with a needle and thread. Still, these look great.
