I have been searching for a tip to make the big magnolia flowers that I have seen on some cakes. Please if anyone knows where to find them please let me know.

ADo you have a photo? Most magnolias are made with flower cutters & gumpaste. I don't recall ever seeing one made with a tip.

Perhaps in this instance 'tip' is referring to ..... HELP or ASSISTANCE tips  

not piping tips  :)

But I agree, bit confusing since OP is asking where to find 'them'

Yes, are you talking about a gumpaste magnolia tutorial or buttercream magnolia tutorial.

Here is a link I booked marked quite awhile ago.

Scroll down a little for the tutorial. I hope this is what you're looking for.

Oooops, I just re read the opening. I forgot you were looking for a tip.
