I love crayons and really enjoy using them for quick sketches in life drawing or for their use of vibrant colours. My favourites are Faber-Castell crayons as they're more buttery than any others!
Pastels are very useful in adding in sharp jolts of colour when life drawing or or just studying from the masters so I tend to use Staedtler Noris Oil Pastels as they offer so much more colour and feel lovely!
As an oil painter first, I do struggle with acrylic but have recently enjoyed using Daler Rowney System 3 Acrylic set as they mix well and don't create too much tackiness which most acrylic paints suffer from!
Over the last decade or so, I've really gotten more into watercolour, though I still think I paint as if using oils! I have a wonderful watercolour set called, Ezigoo Watercolour Paint set. The colours are vibrant, long lasting and mix well.
