About your post on Sennelier Rive Gauche, did you get around to use them much? How do they compare with Camel artist oils? I usually prefer to save the more expensive colours and do base layers with Camel. Wondering if I can use Rive Gauche instead, since they claim to dry faster. Also, do they mix well with other oil paints....Camel, WN, or Schmincke? Thanks.
