Hello, I am making a cake based on a friend's original wedding cake, just 2 bottom layers.  This is for a 50 yr anniversary.  I would like to recreate the white wings on the sides.  What is the best medium for this?  I have made smaller but similar decorations with white chocolate, but I am concerned it would not be sturdy enough in that size.  Heat should not be an issue.  I do not expect outdoor air temp to be above 70, probably in 60s.  It will be indoors, out of the sun.

I would prefer to do a sugar wing as it seems more stable, but I'm not sure of the best way.  Would royal icing work for this?  Is there a more rigid recipe or cooked sugar that I could pipe into these wings?

Please see photo.  Thanks so much for any help!

Yes in my thinking that is what they are.  There probably will be breakage so make extra   I have found piping royal in plastic wrap results in far less breakage than the usual wax paper.  Just be sure it is completely smooth.   To remove slide item to edge of table & slowly pull the plastic wrap down, away w/your other hand under ready to catch it when released.  

White chocolate is also a good choice & can be as stable as royal   Do either as I described above —I’m thinking the cho ones could be made a bit thicker  or you can turn the royal over when dry & pipe over to strengthen 

Ditto everything kakeladi said.  I've only ever piped this type thing (snow flakes) in royal icing one time.  I did have a little breakage, but not nearly as much as I expected.  Just don't make too delicate.

adding cream of tartar to the royal strengthens it as well as using the real egg white recipe rather than the powdered meringue powder -- i would use royal -- i put a swipe of pam oil spray on a paper towel and wipe down the waxed paper so the royal will loosen easily -- i know it sounds counter productive to the royal but if you haven't tried it you don't know how great it works -- it will come off handily by sliding under with a small thin spatula -- and it does not affect the strength of the royal -- 
lynne, don't have a heart attack on me  

I am a complete novice on royal icing and appreciate the tips of using cream of tartar and real egg whites!  A light coat of oil on the wax paper is brilliant.  Thanks, -K8memphis.

K8!!  I almost did ;)   Using plastic wrap worked well for me
