I used a piece of cardboard-box card (can't remember where I got it from but it was 12x12in). I covered the back in fabric to reinforce it and give it some interest. Once that was dry, I trimmed the whole to be an A4 size (8.25x11.75in) with an additional 1in tab. I'll be using A4 sized paper for most of the projects.
I covered the front with gesso primer and let that dry completely. I drew my image with pencil and painted it in using acrylic paint. I finished by adding the silver embellishment with "The Creative Path" embossed with a stylus, punching out the three holes on the side and putting in the three binding clips and adding the lettering.
The final product...and the start of my creative journey:
