When you attach spikes to a bow is there anything special that you have to do? I haven't done any real layered bows so this is a new one for me. I'm working on some christmas ones that have spikes on the bottom, surrounds and then a 4 inch boutique bow in the middle. I've tied the spikes off, I fabric tacked two sets of surrounds together. I tied off the 4 inch bow. Now do I tie them all together again or can I just glue them on top of each other and then put my center knot over it all? I'm confused on this one. Help!
