I used frameshop.com.au for the frames (the prints are an unusual size). I must say I was quite impressed with their service. I ordered on Friday, and they arrived on Wednesday! I'm not sure how that compares to other custom framing, but I was impressed. A great range of different coloured frames and mats, and different glass options, too.
Now they just need to be hung in the girls rooms; the dark haired girl for Louisa, and the fair haired for Lizzie, of course! It makes life easy to have two girls with opposite colouring.
