You can go many places to find this wire. I normally shop at our local home improvement store. You can also find many different sizes of wire at the hobby and craft stores.
I use 20 gauge wire and you can buy them at any hobby and craft store as well as at walmart in the floral department. Make sure you use coffee straws in the cake first and then insert the wire into the straw that way you don't touch the cake with the wire.
Thank you JawdroppingCakes for letting me know to put them in coffee straws. So they are just regular floral wire then?
yes just regular floral wire .some people also just dip them in chocolate instead of putting them in straws
