Crochet

There are poles along Dingwall Main Street ( I have no idea why but perhaps it is to restrict Parking) . Recently there was a kind of festival where there was book reading etc. and one event was yarn bombing.  The poles have all been decorated with crochet. I like this bee one best but I noticed a couple having a giggle at the one I have as an extra. I wonder why???
 I think it is supposed to be a cake!
