I dug out some sparkle cardstock that I bought for some unknown reason ages ago, and starting searching the internet again for good silhouette shapes. The little miss is quite fond of cats, so I thought a cute little black sparkly cat would look great on the light switch in her room. I traced a shape I liked (that wouldn't be too difficult to cut out) and then copied it onto the back of my black sparkly paper and cut it out, then attached it to the wall with blu-tack.
The little miss noticed it straight away when she went into her room and loved it! She said it looks just like our kitty (who also happens to be black). It was super easy, and I already have the sparkly paper, so I've started collecting ideas of other silhouettes that I can cut out to make for next year's school gala crafts.
