How about a little something from Pike Academy? Did you know every now and then we throw out a little tutorial? You can access them anytime by clicking on Pike's Academy on the left hand side of the blog. Here is a little tutorial on making a bow to "top off" that project you are making.
Don't just make them for cards...how about the center of flowers, or a 3D turkey tail feather or bunny butt....so many possibilities. Use less ribbon for thicker ribbons or smaller bows. Make the size smaller by wrapping the ribbon around 2 fingers or make it huge by wrapping 4. Play around with it...easy and fun!
