Woodcarving advice please

[geoff]

I fancy making one of those carved wooden cups you see on bushcraft programmes by Ray Mears and others. I've found out that the usual wood is Scandinavian Birch
Does anyone know if common or garden silver birch is OK?

Mr in Pots who carves stuff says to Google 'Kuksa' for info on carving a cup.
