You'll need 5 magazine pages.
Fold each edge in toward the center, so that a seam is created.
Lay all 5 pieces end to end so that you can use the chart above to make lines for your cuts. For 10.5 inch strips with straight sides, the cuts are at 3.75 inches, then at 6.75 inches. If you want rounded edges and bigger center, the cuts are at 3.5 inches and then 7 inches.
If you're using a smaller magazine that makes 7 1/2 inch strips, your cuts would be at 2.75 inches and then 4.75 inches OR if you want rounded stars the cuts would be at 2.5 inches and 5 inches.
Once you've made your lines and cuts (cut only to the middle of the seam), tape the strips end to end on the fronts and backs of strips.
Once taped, shape your strip into a star, just as if you were drawing it.
Once you have all of the slits together, tape the top edge of the star together.
Voila! Your star should be able to stand on it's own, or you can hang it somewhere.
