Yes, they are just hot water bottle covers and they're "only" made from granny squares but I'm still very pleased with them.
The reason I'm most pleased is that I joined the squares up as I went. I'd learned how to do that by reading Lucy's blog - attic24. Thanks for sharing that with us, Lucy!
Now that I know how to join them as I go, I'll never need to spend hours and hours sewing them together.
I wonder what else would look good covered in granny squares? :oD
