how are you going to present it? framed would suit how amazing it is, but i guess glass would hide the knittedness...
but great work, i hope she loves it!
I'm just going to sew it onto felt backing, with a sleeve at the top and a sleeve at the bottom to slide a thin piece of wood or some other rigid material to give it some strength and structure... I'll string some rope on the back so it can be hung on a nail.
