Why not have some fun and make some bats for Halloween? They only take about 8g of wool, and are a great way to use up any oddments. I have knitted all these bats with doubleknit, and with 2.5mm needles this gives the bats quite a firm structure for their wings. You could make your bats into a bat bunting, or put them on thin elastic to make them fun to play with. I am using mine as decorations, and they keep appearing in different places in my flat.
