Making an experiment with coulored crayons

I also have also some prismacolors in a transparent pack:

It is nice and compact.  I just miss the old ones with the cardboard, with the same concept.  The cardboard ones had more crayons.  I just have to get used to this new packaging,  I don't know how long it will take.  I used all those crayons with the graph paper:

I love the result!  I may not use all the crayons as above.  I am thinking more taking one set and play with the coulors.
