Tangles used: Newell, Auraknot, Flux, Scrawlz(variation). Not sure that the center, or the intertwined lines is actually a tangle.
If you have not all ready done so, would encourage you to visit The Bright Owl to look at what others have done with this template. Check back frequently throughout the week as there are always new additions.
Thanks for visiting. As always, comments are welcomed, encouraged, and appreciated.
