A few years back I made a blue and a white Totoro, and wrote up the patterns on my livejournal (White Totoro , Blue Totoro ). Since then I've been wanting to make a grey one, and to perfect the original two patterns. In the end I did that, and also adapted the pattern for the white Totoro to make a small blue one to go with the grey one, and a tiny white one to complete the set.
This might be easier to explain in photos!
Here's the large grey Totoro, which is about 9" tall, with the small blue Totoro (4.25" tall) and the tiny white one (1.75"). To be honest, the two smaller ones aren't quite to scale with the grey one, but it would have been too difficult to make a white one small enough without changing the type of yarn, which I didn't want to do.
These are the updated blue and white Totoros. The blue one is about 8" tall and the white one is 4.25" tall. When I started remaking them I changed them quite a bit - I obviously crochet a lot tighter now that I did when I made them originally. The grey Totoro and this blue one have a similar pattern, the grey one is a bit taller but the ears are shorter.
The white Totoro and the small blue one are the same pattern, just with extra elements (tummy, arms) for the blue one.
Here you can see the two different sizes of blue and white Totoros, I'm happy that I got the scale pretty much right for both sets.
