Useful for Creators but a Bit Much
This Sketch Plan and Create Sketchbook by Trinity Stampa is well thought out but a bit on the heavy side for want of a better word.
Lots of papers to suit a crafters paper-size imagination and it even includes a traceable hard stencil to aid in creativity.
For those who wish to think about what card they'll be creating next and want to jot down their ideas, this is for you. You won't be disappointed.
