I've been looking at favour boxes but felt they were a little beyond my budget however I found the below website which does an amazing range, some of which are for as little as 15p per box! They don't come with any decoration but even the flowers are reasonable for 8p each!

Therefore you can still get "crafty" because the boxes are plain and require decoration!
