My Brownies used to love making a house for a fairy ! I told them that some fairies were due to visit the area but they were very shy, so they wouldn't see them, but they needed some nice places to stay. The idea was that they would find some big tree roots and then gather leaves, bits of sheeps wool, stones - anything that could be found lying around (not breaking leaves off trees etc) and then use different areas of the tree roots as the rooms of the house. Some were really imaginative with "slides" (big leaves) from upper to lower rooms, comfy sheepswool beds, tables, chairs etc - it's amazing how this fires the imagination. They also liked pond dipping, cooking a mini burger on an upturned empty tin can with holes made with a can opener in the bottom and a tea-light under it and on pack holiday they even liked learning to clean the toilets, peel potatoes, tie-dye a t-shirt and, (randomly), sit and wash their socks and peg them out on a line. (interesting to see how some managed to fix the socks to the line even though their pegs were upside down!)
