aww they look lovely but soo expensive for what they really are..
I came across these people at the hobbycraft show I went to, alto smaller then those, but I got some stuff to do a name plate for door, and you can paint and decorate the wooden cutouts yourself. I got the plaque his name and some little shapes like stars and rockets etc for 5.50 , sure you can find the letters cheaper..actually Hobbycraft stores I think have them..but they also a bit on the expensive side!
