Is there anywhere in Ontario to order 3-4" gumpaste roses from? We found a place in th US but they seem a bit pricey.

You can buy readymade blue fondant from BulkBarn and make your own. The most basic roses are not that difficult to make. BB also sells tools like cutters and small rolling pins.

P e t r a I n t e r n a t i o n a l sells them. Sweetopia recommends them.They are in Mississauga.

edit: you may have to buy several from these people. So my suggestion may or may not help.

Have you tried this website?

I don't know how the prices compare to what you have already looked at but it might help. Good luck!
