This wire that the stars are on?.. I'll be going to Michaels craft store tomorrow to get some more cake boxes, Can I get it there?

Also, I've always made my own MMF and I saw in a post earlier that somebody addd corn syrup to theirs to make it more pliable.. How much should I add to my MMF and when Do I add it?

Micheal's will have it (florist wire) . . . . . . usually 18 - 20 will do for most applications . . . but it will depend on what you are trying to support . . . finer if small light weight items are being suspended . . . heavier if larger heavier items are in use . . . you will want to wrap the wire and probably use straws in your cake to channel the wires into your cake for better support (and wires not coming in contact with your cake) . . . hth

I use 20 to 26 gauge. Larger the number the less weight it will hold. I use the higher gauge when I want to wrap it around a pencil instead of leaving it straight. It is kind of fun that way.
