how do I make those dried orange slices for decorating/smelling nice ?

[christMAScomesbutonceayear]

do I just dry them out in a low oven ? am planning to tie them to cinnamon sticks with raffia - have had disasters with pomanders in the past,so a bit unsure...thank you

I know this thread is old, but I too wanted to dry orange slices so found this link for anyone still looking :-)
