My e-mail inbox has been filling up with the same question - "how did you wrap your ribbon shares?" ... as seen in this post from yesterday.
It's so simple ... cut cardboard from the Stampin' Up! designer paper packs 3" x 6", then use a 3/4" Circle Punch to create "notches" to secure the ribbon in place.
As you can see, the punching isn't perfectly measured out ... just eyeballed. No time! ... off to cut more designer paper and ribbon!
