The first card was for a friend of mine who is currently in hospital and I used the challenge from Orange Paperie to use hexagonals as well as stamping. I hope this is acceptable - I did search the blog but could not find anywhere that said challenge entries had to be layouts.
The second card for the birthday of one of my son's friends and I used The Lollipop Ladies challenge #65 using colourful rock candy for inspiration and the added criteria of music.
I also did a card for a family friend using challenge #64 (stripes and flowers) but then realised I had missed the deadline. So many challenge sites now list all their challenges with an end of month deadline regardless of whether they have weekly, fortnightly or monthly challenges and I'm afraid I tend to forget which one's don't - Oh well, here it is anyway.
