I like to use grosgrain ribbon due to it's strength to hold up the weight of a button or two. You really could use any ribbon and either double it or sandwich it with some fusible interfacing. This bookmark actually has buttons on each side of the top. A plain side and a fancy side if you like. It isn't necessary to put buttons on both sides as it tends to make the bookmark too top heavy.
These fun pink bookmarks are merely folded over about an inch on the top and have a couple of fun buttons stacked and tied with twine or ribbon or crochet thread.
This one appears to be my favorite. I used some ribbon that my sister had wrapped my birthday present with. The fun flowers are perfect with this color combination.
I think once you get started you will find a ton of ideas just flood forth. The combinations are endless and the time is minimal for each bookmark. This would even be a good fundraiser item. Now I hope you will see your ribbons and buttons in an entirely new dimension.
Now back to the studio for more creative ideas. This is the season for lots and lots of gift giving and I am one who loves to give handmade gifts. Our family always believed those were the best gifts to give. Lots of time and thought and love put into each and every gift made.
What are you making?
