These sets show some possibilities for layering stars for a fun and unique look! Some are full stars layered and some are cutouts which allow the paper underneath to show through. Doing that extends the use of your paper.
I have found I prefer to separately fold the layers instead of gluing them and then doing one fold. One advantage is that you can move your elements around until your happy with the look. Another is that if you have not glued the star on centered correctly, that will show up when you go to folding it...so I glue at the end when I've chose placements of colors...hope this will inspire you to create some fun color and pattern combinations!
