I also just saw these bows online for cheap - - >
They are labor intensive.
I have made a few, but I did them like the layered spikes on a stacked boutique bow. I now see it's more of a twist pattern then layering spikes.
Looks like you could stack them all together in one stack, then push your needle through the center and fan them out before looping and pulling your knot.
I know our rec squads in town for pee wee football love those bows!
