My wife does a lot of crocheting. She makes baby afghans and then donates them to the local hospital each year at Christmas time, for new mothers.
Needless to say, we have a lot of yarn around the house, which can be a bit of a problem when the cats get rowdy.
At first glance, this jigsaw puzzle looks like it would be easy, but I threw a twist in there. The pieces are all nearly identical in shape, making them a bit tougher.
