Ok, I literally feel so stupid asking this, but I cannot figure it out. I just bought some fat daddio pastry bags. I come home and pull them out, along with my "universal" ateco coupler. Except the coupler doesn't fit. I know sometimes you have to trim the bag, but it's like the bag is too thick for the coupler to grasp the other end. So then I tried my wilton one..and no luck. What coupler do I need to buy??
And will wilton tips fit, or do I need to buy fat daddio tips?

Thanks!

Hmmm..... I don't know. Bump!
