I'm still working my way through the lovely items that Derwent sent me to try out :>) and have been adding things to the review I did of their lightweight, hardback sketchbook at the end of last year, as I've continued to doodle and see what things can do.
This first one is a view of the winter fields - the tin of tinted charcoal pencils was ideal for this and gave a lovely limited colour range of warm and cool that play against each other perfectly. I can see me using these frequently for wintry days. They are fast to work with which is a bonus in our current weather when plein air. They would combine interestingly with other media. Something I've yet to try out. (edit: I have now mixed them with inktense here and will add more links as I try them with other media)
Then I tried out their Academy Tame and Wild Set - also limited colours - whilst waiting for a family member visiting the GP. This was my view from the car :>) It has some pastel sticks in the set but, wanting to keep my hands clean and only having a short wait, I limited myself to the pencils for this. The ochre colour doesn't pick up very well in the scanner sadly - but it's there in areas, particularly the mud splashes on thebottom of the door.
and of course there were the Graphitints, in an earlier post
These were all done in the lightweight A4 sketchbook.
