Here is how I did it:
*Take 3/8 in grosgrain ribbon and wrap it around a 1/4 in wooden dowel rod using wooden clothes pins at the beginning and end to hold them into place.
- I also used 5/8 in grosgrain ribbon wrapped around a 5/16 in wooden dowel rod.
*You can wrap them as close together or spaced apart as you want. The close together the tighter it will turn out once it's done. (I did mine leaving no gaps all the way down)
*Place them on a foiled covered cookie sheet and bake in oven at 275 degrees for 25 minutes. (You can also place them in an aluminum lasagna style pan) The foil is to protect the ribbon.
*When you take them out let them cool off for a few minutes. It doesn't take long, then unclip the close pins and take them off the dowel rods.
THAT'S IT! Now you have korker ribbon ready for hair bows or any other project you have in mind!
