Derwent Inktense Colour Blocks are sticks of vibrant watercolour ink which are incredibly versatile. Use them dry if you like - they're great for covering large areas - but add water and they really come to life! Once dry the colours are fixed (unlike normal watercolour paint), so you can safely work over the top of them. This permanency also makes them ideal for using on fabric such as silk, cotton and canvas, and you can also use them for printing and stamping.

There are many ways you can use Inktense Blocks to create amazing artworks:

* Use dry, then use a brush and water to blend. You can then use dry blocks to add extra detail.

* Apply water direct to the blocks with a brush, just as with normal watercolours. Put two or more blocks side by side before applying the water to all of them, and you can create instant stripes!

* Grate a block into water, or shave bits off it with a sharp knife, then mix and use as a wash

* Apply water to a block then shake it and create paint splatter effects
