I decided just to let it set all bulky as I thought I would be able to carve into it once it was dry. Errrr, NO - it's like concrete once it's dry... it broke the blade on my craft knife! I kid you not. Took ages to sand it back down, I was almost in tears thinking I would have to remake the whole head/torso again.
Once I'd calmed down and it was sanded smooth again I decided to have one more go and wait until it was semi-dry to manipulate it and thankfully I am a lot happier with the result this time. I like the way she is developing, what do you think?
