It's always a nice jump start to getting the brain working in a creative direction. Once the hand starts moving the ideas usually flow.
My go to format is these:
I like the 9X12 size. A little big for travel but I make room for it as feels the most comfortable to me.
Then I doctor it up to my liking on the cover.
I dive into the scrap trunk of painted fabric or create a new piece that I sew onto the cover after
I've painted the edges with acrylic. Yes I do that on my sewing machine. Canvas seems to give the cover longevity and protection from wear.
Over time I found it important to leave a couple pages blank at the front to create an index.It's loose but it helps me find notes, ideas, etc. I want to refer back to.
One piece I have cut to to fit my journal pages. Water down some acrylic, apply with a stencil brush and voila. A grid in which to write.
I'll be back tomorrow with more. Time to feed the cat & get ready for my day job.
