Carol's is part of the January exchange, so it will be coming up in a later post.
Eva made her envelope from a calendar page, and added part of a cool metallic coffee bag (?) to her note.
Here it is without the postal bar code. 1437 refers to the new Islamic year which started in October 2015 (the Islamic calendar is a lunar one, rather than the Gregorian solar calendar).
On the back you can see the Gregorian 2016 new year.
Heleen sent me a postcard of a castle in the Netherlands, since I wrote on her blog I didn't know any. The sheep stamp is fantastic, and is by the same photographer who took the picture of the castle. Heleen even added a little castle stamp.
And Jon sent me a postcard with a painted image of David Bowie. I love the back, too.
