Make 3D, Light-up, Twisted animal Horns!

Step 7 Wrapping in crepe paper.

The crepe paper diffuses the light and gives a really nice glow - see attached photo.  It's very inexpensive.  A layer of crepe paper adds strength and durability to the horns.  It's also great to work with because it's stretchy, and it comes in a million colours, from garish to dull.  You can choose your crepe paper colour to match whatever theme you need - bright and sparkly, cute and pretty, raw and organic, or creepy/horror. 
I tried using paint only, but IMO the crepe paper looked much better on the horns.  

Take the coloured crepe paper out of its packet and cut straight across the top of it.  Make your strip about 4cm (1 ½ inches) wide – if it’s any wider, it will not stretch well. 

I find that foam glue works best for this next part.  It seems to work better than PVA/school glue.  So mix some foam glue with a little water.  I make a mix of 2 parts glue to 1 part water.  

Hold the tip of the horn, and start painting some glue from the base, to about half-way up the horn.  Start wrapping the strip of coloured crepe paper, starting from a fraction below the base. 
Stretch the crepe paper a little, but go carefully – too much stretch, and it will rip as soon as it hits the glue.  If not stretched a little, it will go all baggy.  Overlap the edges as you wrap, but by a very small, miniscule amount.  If a small tear develops, ignore it, and keep wrapping.  Small imperfections look natural - they look like real horns; and anyway, a small tear will be well disguised and almost disappear in the next step.  If the tear is large, then overlap the crepe paper slightly more on the next turn.  But don’t overlap too much – you want the lights to be able to shine through the thinness of the crepe paper. 

Flip the horn and paint the top half with the foam glue/water mix, and wrap the crepe paper up to just past the tip of the horn.  The horn could probably be stood on a heavy bottle while the top half gets painted and papered.  Tuck the extra crepe paper under at the base and over at the tip of the horns, and paint some glue on to seal it.  It gives a nice edge, and hides the green plant tie.

The crepe paper will adhere nicely to the glue, but it will start to look slightly weird and areas of the soft plant tie will start to show in parts.  The colour in the crepe paper may even run slightly in parts.  This is all OK – it looks kind of raw and organic, and it will mostly be covered by the glitter paint and glue mix in the next step.  Go straight on to the next step - don't let it dry.  But it's not a catastrophe if it does dry a little.
