I would sew it for sure but if you decide to do the headaband 2 should be enough. I was almost able to squeeze into one headband and I'm a 0 so I would think 2 would enough for a 6. I would charge $60. Well I guess it depends on the cost of your supplies. I would do 6 yards per layer so that is 18 yards and I pay .50 per yard so that is only $9+ less thank a $1 for elastic. The bees will probably be what cost the most. You could make sone ribbon bees and attach them.
