The answer is "make too much". Even if you measure around each scallop all around, it hard to calculate how much you loose in each of the "dents" and the diagonal seams. Just measure, get close, and add extra to make too much. remember to make Bias binding for scallops so they lay smooth. Which method are you using? are you following somebody's, like Eleanor Burns you-tube and using her scalloping tool? or some one elses?
