If you'd like to make them some supplies you may use are : packaging tape, scrapbook paper, scissors, stickers, markers, hole punch/lacey edge punch, and no, not a cat (-:
Begin by cutting a rectangle piece of scrapbook paper, narrower than the packaging tape.
Use punches, markers, and sticker to decorate.
Now pull some of the tape, and lay the bookmark, front facing down onto the tape, like in the picture.
Then fold the tape over it, covering the back.
Trim the edges, and if you'd like, punch a hole and thread ribbon or yarn through it. You may also add a bead if you want.
Well, have fun!!!
