Sticky notes will work, but there is a specific way to fold the modules so that the adhesive portion doesn’t get in the way.
If using sticky notes, having the adhesive side on the back will make folding easier and the added grip can be helpful in making more precise folds.
If using sticky notes, make sure the vertical line goes through the adhesive.
If using sticky notes, make sure you fold in on the side with the adhesive so the sticky portion is no longer showing.
The 7th and 8th modules are a little trickier because the pieces begin to overlap, but still follow the same concept. When adding the 7th piece, make sure the front of the first piece is in-between the back flaps of the 7th piece. Slide the 8th piece into place, following the same pattern as the rest of the pieces with the front of the piece fitting in-between the 2 folded-in edges of the 7th piece and back flaps on either side of the first piece. When folding the flaps back edges in, you will notice that there is already another piece in the way. Fold the flaps in on either side of the piece already in the crevice, by holding the middle piece to the side while folding the edges in on either side. Do this with both the edges of the 7th piece as well as the edges of the 8th piece. You should now have a fully interlocked octagonal shape. This is the untransformed version of the ninja star.
