I don't want to have to buy a whole new set of tips but the class uses Ateco tips, is there a chart somewhere that shows an equivalent Wilton tip that I could use?....thanks

I have some wilton tips at home and at work we use ateco. They are the exact same numbers.

the only difference I find is their couplers. I would definitly get a few ateco couplers they don't have the annoying cut out on it. so you can you it to make easy and nice balloons.

thank you for the info!
