Today I had an epiphany moment!
I've struggled for ages to get a smooth finish with Paperclay, but following advice from a member on Dixie Redmond's Izannah Walker Workshop I've discovered that it's ok to sand it wet!!! This is much easier for me, because it is so like cleaning porcelain greenware. I hated the dust of dry sanding....and struggled to see what I was doing!! What a simple discovery, and it I've tried it out today - to great effect!
Thanks Artis Corwin!! You made my life a little easier today :0)
