WIP - Crochet - Temperature Blanket - Week 21

Even though we have had some really cold weather lately we have also had some unusually warm nights. Especially for this time of year. In fact we had temperatures in the 20's  the other night. And since my blanket is based on the highest temperature for the day I've had to crochet some green rows even though cold fronts have come through and made the daytime temperatures very, very cold. Hence the green rows. The weather bureau has stated that we wont be getting many temperatures in the 20°C's range for quite a while.
