Some sewing experience recommended but it's easier to make than it looks.
Step 1: Supplies
What you need:
Ribbon (Any type of cloth ribbon will work. The type that you can curl with scissors won't work)
If the ribbon has wire in the edges, remove the wire once your pieces of ribbon have been cut by simply pulling the end of the wire straight out. If the wire isn't already sticking out, push the edge upwards till a small part of the wire is sticking upwards. This small part can be bent down and pulled out.
I usually use ribbon that is 1.5 inches wide, in which case the length of the pieces should be about 3 inches.
