I recently customised a 'My Little Pony' as a wedding present, it's been a long time since I've done a custom toy, about 5 years I think. I actually really enjoyed it, nice to work in a different format. The birdhouse is made of balsa wood and I added extra elements to the ponies body using Milliput.
I also asked my friend and toy cutomising supremo Pete Folwer to furnish a pony with his artwork, here's what he came up with, pretty special I'm sure you'll agree.
Cheers Pete!
