I saw this DIY bookmark idea while cruising the archives of a new favorite blog called d.Sharp Journal. Re-use old envelopes by cutting the corners to serve as disposable, notable, bookmarks. I love the idea. I will use anything within reaching distance as a bookmark; receipts, napkins, bobby pins, you name it. Not only do I adore the re-use/recycle aspect of this project, but I love the ability to costumize each bookmark with notes. How fun?
