some extra precreases for melisande's pentagonal double star which will make a later step considerably easier and definitely more accurate (at least for me)
when folding melisande's pentagonal double star I was bothered by the fact that for her step 5 there are no precreases and so it's not so easy to make it regular. so I reopened the model afterwards and had a look for references. luckily there's a simple one : )
note that step 5 is folded on the back of the paper and these precreases are for new mountain folds. in this case precreasing is easier when done as valley folds, so this is colour side up.
note, too, that the reference point is just the tip of the central pentagon from the twist fold.
