"Beauty of handmade lies in their imperfections, anything perfect is machine-made"
First of all let me tell you that my cat is a really big fan of paper balls. Nothing is better then a paper ball, not even the most expensive toys on the market.
She was used as well to "bring it back"... yeah like a little sweet dog hahaha. :) ...but since we moved she's not into it that much so we usually end up trowing the ball and, after a bit of playing she just leaves it somewere really well hidden.... to start playing again with it in the middle of the night (you can imagine were the paper ball ends when we wake up).
Said so... I found a really cool crochet pattern for a simple cat toy, a DIY really easy to make. It's done reclicling one or half toilet paper tube and, as it doesn't need lots of yarn, it can be also done with pieces left from other crafts.
