My paints are mainly Winsor and Newton in pans and tubes but I have some Sennelier and some Schminke watercolours too .I fill the pans from the tubes as I go.I have some Schminke artists goauche and W/N goauche in tubes. Some of these paints are not very lightfast-the pinks usually.Also here are some FW acrylic inks and I have Atelier interactive acrylics,which dry slower than normal acrylics, but I haven't used them much yet!
Buying pastels is addictive and can get expensive especially if you like Unisons and Sennelier. I also buy cheap ones from a local art shop to block in at the beginning of a painting to save the expensive ones! I also tried a set of Pan pastels when they first came out but haven't really used them much. A few Derwent and Faber Castell pastel pencils or a charcoal pencil is great for finishing off details.
This includes a tin of really old watercolour pencils(I've had some of them since school!!),sketch books,a pencil case of drawing pens,various graphite pencils ranging from 4H to 4B and some Derwent Inktense pencils,which are watersoluble.
Also I have a water brush so I don't have to take out pots of water.These are very handy.
