Hello again! I have just read the comments left about the advent bunting and thought I would post a picture of a quicker alternative - I didn't have time to do the bunting last year so just made the 24 bags out of Christmassy fabric. I then hung strips of ribbon down and attached the bags using red spray painted wooden pegs (or you can quite often buy christmas themed pegs or similar). I also attached a card to each bag (also using the peg) - the cards were numbered 1 to 24.
You could also attach them garland like - horizontally to a piece of string or ribbon.
