I always try to put in the following:
blank used (Wood, acrylic, metal, other materials)
the hardware used (Style and/or plating) and from where I get it (if I remember)
and the finishing process used. (CA, Polish, Wax, MM, Sanded, natural, etc.)
I've been collecting it in Excel and then adding it to the post (here on the forum) adding it to a business card in the pen display box.
I haven't gotten it organized to make it really easy, yet. Mostly stays on the excel spreadsheet. :biggrin:
