My first quilt, ever! For this Minecraft Creeper quilt I cut blocks 5" by 5", using six different shades of green. (The seventh I forgot about, so ended up using that to make the binding.) There is an eighth shade that I used for the backing. I did 16 squares across and 20 down. I wanted the finished quilt to be big enough to cover an IKEA single/twin duvet underneath it.
