i made my sil a nappy cake, using newborn nappies, muslins, hooded towel and a blanket, and got some lovely baby boy blue ribbon to tie around it. and a nice teddy on top.
they are so easy to make by yourself, just get loads of elastic bands, cheap and look brilliant and mean so much more when you make it.
the ready made ones are a complete rip off, hugely overpriced for something so simple to make, id suggest any one to give it a go, ill deffinatly be making one for any future bumps in my family.
