In Sweden it's really hot now at least where I live. But I managed to make a bookcard in the heat for En Liten Butik that is up today.
I used this Swedish tutorial when I made the card, but if you search for bookcard in English there are plenty tutorials out there. This card is a bit smaller then the bookcard I have done earlier.
Here is some pictures, you can find more at En Liten Butik's blog.
Have a nice day! // Cissi
