DIY: hand bound journal This is so cool! I have to try it! Think of having all the journals you want, even tips on how to construct it so that you can add pictures, etc, without a page flare resulting.
portfolio binding/(the hemp leaf) book binding you could use interesting material for the cover--something that signifies architecture/modeling/plaquemine. i think hand binding your work, and printing on textured paper will look sleek--especially the watercolors.
