I think pixcoins would be better, more pixcoin sinks, but people have many pixcoins and there are like only a few artists… probably will need to cost 1000+ pc
Not for ppt because getting enough ppt for item commissions is already so much waiting, if for ppt maybe only a few ppt and not like hundreds. Pc would make it more affordable for people anyway.

I like the idea of a choice, whether you want it to be added in hoards/in game shop (a place only for accessories) or giving the copies out yourself. Would it be like FR where you can choose how many copies of them? How would the pricing work for accessories that are more complex, would they be same price as ones that are more simple? Would it be set price or depending on complexity? Hmm why would it cost to reapply?? Would the copy of the accessory disappear after using it on a pet and removing it?
