whoops sorry for misunderstood. I thought we're talking about the "sweet & sour apple hulahop". Honestly they are all stack of orange slices. I just shift their orange slice's hue in alternate thru photoshop, hence i just turned them out into faux lemon slices.
i honestly i had a hard time to choose the right same size as Granny Smith apple. Washington apple are quite stay the same size(unless they are young), hence granny smith are bit smaller than washington red apples. many thanks for your thoughtful opinion & curiosity.
