Free Instructions: Loopy Surround-a-Bow Surrounds Surround
Here are some instructions to get started. You can alter them to your own preferences. For instance, I hot glue mine instead of sew. Also, I make bows that don't have a bottom bow. I just have spikes as my bottom layer. HTH
Also, a lot of people prefer to turn the bottom bow upside down when assembling. It seems to make the whole thing lay better.
