This activity pack is comprised of four activity sheets, a set of instructions, pack of paper clips and paper test strips. 
The pack of activity sheets is primarily aimed at those purchasing one of the 5/10ml sets. Providing a format to follow and guide for how to initially experiment with the natural Inks and a space to document the color shifts you're producing. With each set/ kit providing the opportunity to produce 10-24 colors, keeping track of what you're making is no small fete, so having a space where this is all recorded in a structured way can really help when moving on to your own creations. 
If purchasing a kit/ set, it is not crucial or detrimental to not have an activity pack. However as a top up/ addition to the sets, they're a great way to structure the play you're having in a medium you may not have worked in before.
