As a group we had to bring in objects relating to one of our themes to make a 3D alphabet. Our theme was nature and so we decided to predominantly use leaves to cut the letters out of.
I think that the first alphabet is effective as the letters are sharp and clear against the white paper. However I think that we could have somehow attached parts of the letter to leaf so that they imitated the letters more (e.g. B having the holes in the middle). I think that both alphabets are good as we used a range of coloured leaves and therefore creates variety.
