Canford Cardstock, as used by David, is sometimes difficult to find. I have used Fabriano Titiano which is fine although is less good at taking erasure and has a slight bubbly texture. I have also used a blue or sugar bag colour paper from Ruscombe Mill in France, similar to that used by Prud'hon, although the sheets I have are quite light (in weight). What other papers have forum members found suitable for work similar to David's video?
